James Zern f88666eb47 webp_js/*.html: fix canvas mapping 
after:
24d7f9cb Switch code to SDL2.

fixes:
webp_wasm.js:1 Uncaught TypeError: Cannot read properties of null
    (reading 'addEventListener')
    at Object.registerOrRemoveHandler (webp_wasm.js:1:101330)
    at registerMouseEventCallback (webp_wasm.js:1:154227)
    at _emscripten_set_mousemove_callback_on_thread (webp_wasm.js:1:155015)
    ...

The SDL2 port forces the canvas id to '#canvas':
324df6865a/src/video/emscripten/SDL_emscriptenvideo.c (L210)

This change maps '#output_canvas' to this entry in specialHTMLTargets[]:
https://emscripten.org/docs/api_reference/html5.h.html

https://github.com/libsdl-org/SDL/issues/5260 &
https://github.com/emscripten-ports/SDL2/issues/130 may also be related.

WebP codec is a library to encode and decode images in WebP format. This package contains the library that can be used in other programs to add WebP support, as well as the command line tools 'cwebp' and 'dwebp' to compress and decompress images respectively.

See https://developers.google.com/speed/webp for details on the image format.
