C plugin API assignments to strL columns

[Jon Rothbaum]

Can you update the C plugin API to have more of the API calls available in python or Java? Specifically, I want to be able to assign to strL string and binary columns, which is possible in python and Java, but not in C. I've got a hacky, slow, I/O-based workaround for strL columns when reading parquet files (https://github.com/jrothbaum/stata_parquet_io) and I don't want to use python (requires users having the proper virtual environment and is ....SLOW....) or Java.
