opl: Use uint64_t for microsecond times.

Previous revamping of the OPL library changed delay times from ms
to us, and switched to 64-bit times for storage for them. However
this type change was botched and some functions were still using
32-bit arguments. Change to 64-bit types.

Thanks Quasar for reporting this. This fixes #438.
