Compile Typst/LaTeX as you write

[fabawi]

Currently Typst supports PDF, SVG, and canvas compilation, however, compilation has to be explicitly triggered. For canvas output, it needs to:

• Compile Typst/LaTeX on save
• Perform compilation progressively
• Transmit feedback from canvas viewer to the renderer to specify pages being currently viewed
• Render changes rather than re-render the entire document

@seofernando25 #105 has been merged, thank you!

It seems #105 works just fine for auto-compile on save. Independent of this pull request, some additional features and minor modifications need to be implemented for it to not interrupt the editing flow:

• Disable the compile notification when auto-compile on save is enabled (checked)
• "Auto-compile on project open" results in double compilation when auto-compile on save is enabled (checked) and the current document is the one being auto-compiled
• If the compilation is running, it should first stop the compilation before re-compiling on save. Otherwise, it would trigger an error when the saving interval is shorter than the compile time which is especially problematic for larger LaTeX documents
• The renderers (SVG, PDF, and Canvas) should preserve the current position and avoid showing a loading page when re-rendering is done (although this should be the case when re-rendering through any trigger and not specific to auto-compile on save, but the latter is where this issue becomes more significant)
