Added traverse and sequence functions for Option

[1eyewonder]

Proposed Changes

Added traverse and sequence functions for both Option and AsyncOption types. I made this due to discussion in the discord channel and thought it may be pretty straight forward.

Functions added:

• List.traverseOptionM
• List.traverseAsyncOptionM
• List.sequenceOptionM
• List.sequenceAsyncOptionM

Types of changes

• New feature (non-breaking change which adds functionality)

• Build and tests pass locally
• I have added tests that prove my fix is effective or that my feature works (if appropriate)

Further comments

If the behavior matches what is expected, let me know and I can create the documentation as well 😄

Do we think the applicative versions should be added as well? I didn't see an immediate use case but I know pblasucci in the discord was the one with the use case
