Should gatsby-plugin-sharp handle BMP image files?

[Jeff-Tian]

See lovell/sharp#3509, the sharp doesn't support BMP image natively. Should then gatsby-plugin-sharp handle BMP image files?

If should, then a wrapper is needed before calling sharp. That wrapper will detect the image's first 2 bytes to determine if it's a BMP-type image, and then use bmp-js to decode the file before pipes into sharp for a BMP-type image.

function isBitmap(buffer) {
  return buffer[0] === 0x42 && buffer[1] === 0x4d
}

If not, then a site containing a BMP image file will stop building and exit when met this file. How do we solve this building halt issue?

What do you think is the best way to handle BMP images?

I see there is a safe-sharp which is kind of a wrapper for real sharp. Is it a good idea to wrap the BMP detecting and decoding logic there?
