bundle should be able to inline images

In order to produce consistent documentation with images I need to inline images (SVG, PNG, Jpeg) as base64 with proper mimetype. AI build a wrapper script with a shell function inline_images that does the job for me:

$REDOCLY bundle "$src" -o "$out_json" --ext json 
inline_images "$out_json" "$src"

It works fine with input in yaml:

<img style="float:right; margin:0 0 1.2em 1.2em; max-width:50%; height:auto;" src="../images/partner_logic.svg" alt="Partner SYNC Logik" />

converted to:

<img style="float:right; margin:0 0 1.2em 1.2em; max-width:50%; height:auto;" src="data:image/svg+xml;base64,PD94bWwgdmVy...

But I think redocly should be able to do inlining and setting mimetype by filename extension (.svg > image/svg+xml) for most used file types like svg and png.

Start by tracing the TypeScript implementation of the bundle command and how image references are handled. Check SVG, PNG, and JPEG inputs and their filename-derived MIME types; done means bundled output contains base64 data URLs with correct MIME types. The issue names no source files or tests, so locate the relevant entry point and test coverage first.
