fix: api-types: add support for lto 9 tape density

lto 9 tapes have a new density code which leads to these tapes not
being recognized properly. add the new density code and TapeDensity to
improve lto 9 support. since the documentation states that we support
lto 5 and above this constitutes a bug fix for lto 9 support.
