a08de19922 LibGfx/PortableFormat: Use FixedArray::unchecked_at 
This allows us to drop from 7% to 5% passed on `add_pixels` when using
`image` to do conversions from JPEG to PPM.

44905ed395 LibGfx/PortableFormat: Write to the output stream row by row 
This is done by adding an intermediate buffer and flush it at the end of
every row. This makes the `add_pixels` method to drop from 50% to 7% in
profiles.

d4d3c3f262 LibGfx/PortableFormat+image: Make encode take a Stream 
As we directly write to the stream, we don't need to store a copy of the
entire image in memory. However, writing to a stream is heavier on the
CPU than to a ByteBuffer. This commit unfortunately makes `add_pixels`
two times slower.
