CLI tunable option does not have an affect using saved parser -- needs error/warning

When using the CLI with the --parser option to use a saved parser, the -T option to set tunables has no affect. Instead, Daffodil uses the values of tunables set at schema compilation time.

This is probably the correct behavior since it could potentially cause odd behavior to have different tunables for schema compilation and schema parsing, but there is no warning or error message that they are ignored and have no affect. So Daffodil just silently ignores the tunable values, which can be confusing if you are expecting a different behavior.
