Convert a list of band names to an index or a slice

Parameters
----------
bandIndex: iterable or `object`
    Index to specify a band or list of bands,
    usually a string or enum.
    For example `bandIndex` can be
    `"R"` or `["R", "G", "B"]` or `[Band.R, Band.G, Band.B]`,
    if `Band` is an enum.

Returns
-------
bandNames: `list`
    Names of the bands in the slice
