Add all parameters of the JPEG XL encoder to the web gui

[dhcgn]

Add all encoding features of the JpegXl encoder to the plugin. At moment only Quality and Effort are exposed.

Missing:

• maxError
• brotli_effort
• progressive
• resampling

JPEG XL encoder v0.7.0 ab775e2 [AVX2,SSE4,SSSE3,Scalar]
Usage: D:\DEV\jxl-for-lightroom\converter\assets\cjxl.exe INPUT OUTPUT [OPTIONS...]
 INPUT
    the input can be PNG, APNG, GIF, JPEG, PPM, PFM, or PGX
 OUTPUT
    the compressed JXL output file (can be omitted for benchmarking)
 -d maxError, --distance=maxError
    Max. butteraugli distance, lower = higher quality. Range: 0 .. 25.
    0.0 = mathematically lossless. Default for already-lossy input (JPEG/GIF).
    1.0 = visually lossless. Default for other input.
    Recommended range: 0.5 .. 3.0.
 -q QUALITY, --quality=QUALITY
    Quality setting (is remapped to --distance). Range: -inf .. 100.
    100 = mathematically lossless. Default for already-lossy input (JPEG/GIF).
    Positive quality values roughly match libjpeg quality.
 -e EFFORT, --effort=EFFORT
    Encoder effort setting. Range: 1 .. 9.
    Default: 7. Higher number is more effort (slower).
 --brotli_effort=B_EFFORT
    Brotli effort setting. Range: 0 .. 11.
    Default: -1 (based on EFFORT). Higher number is more effort (slower).
 -p, --progressive
    Enable progressive/responsive decoding.
 --resampling=-1|1|2|4|8
    Subsample all color channels by this factor, or use -1 to choose the resampling factor based on distance.
 -v, --verbose
    Verbose output; can be repeated, also applies to help (!).
 -h, --help
    Prints this help message (use -v to see more options).
