Lists do not support values that contain a semi-colon

The current curation format for BCs and Specializations are spreadsheets. Lists that are entered into one cell need to have their values separated by semi-colons. For this reason values in a list can currently not have semi-colons.
Example (KFSS): `Marked paraparesis or hemiparesis, moderate quadriparesis; or monoplegia`
Values with semi-colons will be split when creating lists in the YAML files that are used for loading into the database.
The JSON payloads from the API will also have the value split in JSON lists.
