Need to double check the PAM Name keywords vs. their H/V positions

Is your feature request related to a problem? Please describe. The PAM name Keywords CFAMNAME, DPAMNAME, FPMAMNAME, LSAMNAME, SPAMNAME will be set by the SSC to the closest "Enum" value based on the closest match to the H and V values in the Tables on this webpage. This means that the mechanism might be incorrectly position, but still give a valid PAMNAME keyword.

Describe the solution you'd like We want a check early on the in DRP that checks that the PAMS are within [TBD] units of the desired H and V positions. It would then write the correct Enum to either a new keyword or overwrite the previous value (while still saving the original somehow). We might want some kind of step function that is called "update_headers", where we'd put other similar types of checks or adjustments.
