`import_(body)`

    Creates read group sets by asynchronously importing the provided information. The caller must have WRITE permissions to the dataset.

    Notes on BAM import:
    - Tags will be converted to strings - tag types are not preserved
    - Comments (@CO) in the input file header are not imported
    - Original order of reference headers is not preserved
    - Any reverse stranded unmapped reads will be reverse complemented, and their qualities (and "BQ" tag, if any) will be reversed
    - Unmapped reads will be stripped of positional information (referenceName and position)

      body: object, The request body. (required)
        The object takes the form of:

    { # The read group set import request.
        "referenceSetId": "A String", # The reference set to which the imported read group sets are aligned to, if any. The reference names of this reference set must be a superset of those found in the imported file headers.

`update(readGroupSetId, body)`

    Updates a read group set.

    Args:
      readGroupSetId: string, The ID of the read group set to be updated. The caller must have WRITE permissions to the dataset associated with this read group set. (required)
      body: object, The request body. (required)
        The object takes the form of:
