Add CellSens and Trestle to the fs-lite lists

See #6693.

Adding trestle to the fs-lite list results in #9233.

CellSens is likewise broken with fs-lite.

Based on past discussions with @melissalinkert my understanding was that both are either multi file or directory based formats which are unsupported with fs-lite due to the munging that happens under /OMERO/Files. I'm not even sure these would be detected properly without file extensions?

CellSens doesn't appear to work at all. Strangely, trestle does, so I'm not sure exactly what gets transferred server-side, but it looks OK apart from the corruption in some images (which looks like an issue with tile offsets being miscalculated rather than the image being absent per se).

[melissalinkert]

Right, I forgot about the single-file requirement for fs-lite. Trestle is likely only (sort of) working because only one file is strictly necessary - so it should be detected correctly, but something else is going wrong to cause the tiles to be read incorrectly.

This branch has already been pulled out of the 4.4.4 builds, but feel free to just close without merging if desired.

@rleigh-dundee suggests closing, since this will now be completely handled by fs-lite.
