don't rename hdf file when clipped

[slager]

Currently, if clipping occurs during preprocessing, the preprocessed hdf file has "_clip" appended before the extension. This requires special handling downstream in BirdFlowPipeline and BirdFlowPy.

This could potentially be removed and replaced with a metadata field inside the file indicating clipping status.

I dropped "_clip" from the hdf file name in #166 however I still haven't added clip information to metadata.

• Add clip information to metadata while preprocessing.
  • Flag to indicate that it is clipped
  • Possibly vector data on clipping polygon.
    • Do not use terra's vector format as it contains pointers/environments that will break things.
    • sf objects might be OK but I'd like to avoid any additional internal classes.
    • Possibly save the clip in raster (matrix) format with cells that align with the output projection?
    • Possibly save just the polygon's point coordinates in the final CRS - could get ugly with multi-part + holes.
    • Look to see if sf objects can be converted to standard data frame or matrix in a way that can easily be reversed.
