Support high-quality image uploading

[akiomik]

Currently:

• Converted to bitmap
• Resize image if necessary
• Compress bitmap as jpeg
• Upload jpeg

Expected:

• Resize or compress if the size is larger than 1000px or 300KB
• Upload in its original format

	fun convertToUploadableImage(source: ImageDecoder.Source): ByteArray {
	val bitmap = resizeImage(ImageDecoder.decodeBitmap(source))
	val stream = ByteArrayOutputStream()
	bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream)
	return stream.toByteArray()
	}

Maybe my understanding of the restrictions is wrong? (Someone uploads an image of 2000px height)

bsky.social seems to support images up to 2000x2000px and 1MB.
