add packages odin, ols

[flp5]

Testing the changes

• I tested the changes in this PR: briefly

odins tests succeed but nothing beyond that

New package

• This new package conforms to the package requirements: YES

Local build testing

• I built this PR locally for my native architecture, x86_64-glibc
• I (tried to) build this PR locally for these architectures:
  • aarch64-musl
  • armv7l
  • armv6l-musl

arms do not (cross)build, for some reason odins build script doesn't pick up on the arch(it uses uname -m to determine it) and tries to use -march=native instead of intended -mcpu=native
