The [documentation of it.fits](https://docs.astropy.org/en/v3.2.3/io/fits/index.html#working-with-compressed-files) states that bzip2 does not support update/append. While the [`bz2` python documentation](https://docs.python.org/3/library/bz2.html) states that it's supported. So we might investigate if we can add update/append for io.fits with bzip.

As the
gzipmodule also providesamodes, that part of_try_read_compressedmay have to updated as well.
