* Update to 1.82
* Install the binary using the cmake toolchain while here, and then
switch to the post-install target for the icons that cmake does not
install.
Upstream issue: https://github.com/8bitbubsy/ft2-clone/issues/51
Rename the audio/fasttracker2 package to audio/ft2-clone to align with
the upstream naming convention. Update the package to version 1.80.
Note that version 1.81 has been observed to cause segmentation faults
and has therefore been skipped. Additionally, apply recommendations from
portlint, portclippy, and portfmt.
