Add ELECOM Mouse Assistant v5.2.13.000

Add new cask ELECOM Mouse Assistant @ v.5.2.13.000. It configures mouse
options for ELECOM mice. It was previously part of
homebrew-cask-drivers, but that project is deprecated and this cask was
never migrated. The reason for not migrating seemed to be it was missing
a `zap` stanza, which is unecessary if there's an uninstall
stanza. I recreated this cask formula following the cookbook. I also
confirmed the uninstall stanza is configured correctly for this latest
version of the package, which happens to be the same as before.

The cask formula from homebrew-cask-drivers which was referenced in part can be viewed here:
