The zeta parameters to convert.
The desired format for the output zeta object. Must be either 'symbolic' or 'semantic'.
A new zeta object with keys converted to the desired format.
This function takes a zeta object and a desired format as input. It converts
the keys of the zeta object from their current format to the desired format.
If the desired format is 'symbolic', the function maps the keys to their
symbolic counterparts using the ZETA_KEY_MAP. If the desired format is
'semantic', the function maps the keys to their semantic counterparts using
the inverse of ZETA_KEY_MAP.
Converts zeta parameters between symbolic and semantic formats.
