Add build instructions

I'm having a hard time trying to build this project.

I'm not able to make the rust module build by itself if I invoke maturin directly, even if I specifically use maturin 11.3 (as pyproject.toml specifies maturin>=0.11,<0.12)

output from maturin build

  Buildingerror: aborting due to 10 previous errors


Some errors have detailed explanations: E0046, E0050, E0407, E0532, E0599, E0618.

For more information about an error, try `rustc --explain E0046`.

error: could not compile `nuber` due to 11 previous errors
💥 maturin failed
Caused by: Failed to build a native library through cargo
Caused by: Cargo build finished with "exit status: 101": `cargo rustc --message-format json --manifest-path Cargo.toml --lib --`

I would suspect that the rust module was broken, but it seems like you made a commit to the project ~2 weeks ago, so that might not be the case?

This problem disappears if I rather try to invoke maturin through poetry. But based on the error, it seems like maturin doesn't even get invoked at all? Rust-Python bindings seems to be missing.

Do you think you could add some documentation on how to build this project?

Shuting ebooks unorthodoxly

Dunno if you or anyone else thinks this is a problem but shuting down a book with ctrl+c or shuting the window itself won't save current progress

Understanding that saving in every keystroke is infact bloat I'd like to propose savestates to happen in page flipping as well not just when pressing q,this would mitigate the problem of forgeting your last read chapter or having to travel accros multiple pages when reading lots of diffrent books but still not causing unecessery resource usage(if it happens at all)when going up and down a page

to summerize I think it wourld be cool to save on q h and l keystrokes and if not resource heavy ok j and k as well

(PS Seriously I love this e-reader thanks for your effort and Id do a commit myself to help out here if I knew rust at all)

Similar to epy, nuber should display the progress of the book in percentages. I've been busy lately and I don't know when I'll have more free time to continue working on this project (Hopefully in 4 months). So I hope maybe someone can help me create this reader.

Because I know that not a lot of people here know rust, I've written the rust part myself:

--- a/src/book.rs
+++ b/src/book.rs
@@ -90,6 +90,27 @@ impl Book {
             .collect()
     }

+    fn number_of_lines(&mut self) -> Vec<usize> {
+        let current_chapter = self.book.get_current_page();
+        self.set_current_chapter(0);
+
+        let temp_dir = self.temp_dir.path().to_owned();
+        let decorator = Decorator::new(temp_dir.as_path(), self.term_info);
+
+        let mut number_of_lines = Vec::new();
+
+        // iterate over all of the chapters and sum up the lines
+        while self.next_chapter() {
+            let render_tree = parse(self.get_current_str().as_bytes());
+            let lines = render_tree
+                .render(self.term_info.col as usize, decorator)
+                .into_lines();
+            number_of_lines.push(lines.len());
+        }
+        self.set_current_chapter(current_chapter);
+        number_of_lines
+    }
+

This adds the function Book().number_of_lines() which returns all the line numbers of each chapter. All that is left is to display the progress of the book. epy does it quite nicely so I would do something similar.
