Enforce disallowed comment characters across all types

[CBielstein]

Description

Currently, only StatusInfo and MaidenheadBeaconInfo correctly enforce disallowed characters in an ARPS message comment (| or ~). This should be consistent across all packets which support a comment.

Acceptance Criteria

• Check user-specified comments for disallowed characters across all packet types (consider not enforcing for decoded packets, just for sending)
• Find a way to reduce duplication.
