feature: Add parsing support for barrier/reset/delay/duration

[kshyatt-aws]

Issue #, if available: N/A

Description of changes: Allows parsing of QASM files that use reset, barrier, delay and duration instructions. Currently these don't actually apply the reset or barrier (they are no-ops) but this would allow proper implementation of these operations.

Testing done: Unit tests passed locally.
