feat!: make all namedtuples typed, and remove unnormalized option (#24)

    In an early version of regbot, I'd thought about trying to avoid collapsing all values into enums, but I think that's unnecessary so I'm removing the option
    Make all namedtuples type-annotated for editor integration

+Acquire cleaned and structured data about drugs and therapeutics from US regulatory agencies and services:
 
+* ClinicalTrials.gov
+* Drugs@FDA
+* RxClass
+<!-- /description -->
 
+All data returned from regulatory APIs is structured as instances of standard library NamedTuples. This is done to give data structure and rudimentary type annotation (i.e. to benefit code editor and analysis tools) without adding runtime heft or being wedded to particular schema libraries like Pydantic. This may change in the future.
