Refactor filtering by explicit frames

[kalisp]

Changelog Description

Simplified filtering of explicit frames set by artist in Publisher UI. This should be more explicit and safer.
Removed filtering on remainders, eg. single files as there is no real safe way how to get frame pattern there and it doesn't make sense for artist to filter on single file.

Testing notes:

1. publish in your DCC of choice as usuall
2. try set Frames to explicitly filter only specific frames

Do note that clique.assemble creates a clique.Collection where padding is 0 if it has no frame starting with 0 by default. See the assume_padded_when_ambiguous argument to clique.assemble in recent clique versions here.

The question is however whether that could be problematic. If e.g. someone has explicit frame to render 999 but the assembled sequence was 1001-1010 then padding would be zero instead of four meaning we'd get:

• 999.exr
• 1000.exr
• 1001.exr

Instead of:

• 0999.exr
• 1000.exr
• 1001.exr

Whether that's problematic, I'm not sure - just wanted to clarify that.

Also, wouldn't it just work to do:

# Get overlapping frame ranges
included_frames = set(collection.indexes).intersection(frames_to_render)

# Create matching collection that refers to those frames
# and get their filenames.
collection = 
collection.indexes.clear()
collection.indexes.update(included_frames)
return list(collection)

Note that this changes the input collection - if you don't want that you may need to create a copy collection or just do:

included_frames = set(collection.indexes).intersection(frames_to_render)
real_collection = clique.Collection(
    collection.head,
    collection.tail,
    collection.padding,
    indexes=included_frames
)
return list(real_collection)

Didn't test - but code changes make sense.
