Add an opt-in to skip Instagram's exact resolution requirement

Browse Source 
Some users want the assembled HDR JPEG for somewhere other than
Instagram, where the exact 1080x1080/1080x1350/1080x566 match isn't
relevant. A checkbox on the form now lets the whole batch skip that
specific check. The SDR/HDR dimension-match check still always
applies, since that's a technical requirement for the gain map to
align, not an Instagram-specific rule.

Each pair's files must have identical dimensions, matching exactly one of Instagram's feed
resolutions: <strong>1080x1080</strong> (1:1), <strong>1080x1350</strong> (4:5), or
<strong>1080x566</strong> (1.91:1). Assembling more than one pair downloads as a <code>.zip</code>.
HDR can be a regular gain-map JPEG or Lightroom's 32-bit float linear HDR TIFF export; a
TIFF HDR file gives a more precise result than the JPEG gain-map route.
