/**
 * A database library table will be mapped to a sub-library provided by the database library entry
 * in the KiCad symbol/footprint library table.  A single database library config file (managed by
 * this class) may contain more than one table mapping, and each will have its own nickname.
 *
 * The LIB_ID for parts placed from this library will be constructed from the nickname of the
 * database library itself, plus the nickname of the particular sub-library and the value of the
 * key column for the placed part.
 *
 * For example, if a database library is configured with the nickname "PartsDB" and it provides a
 * table called "Capacitors", with `key_col` set to "Part Number", the LIB_ID for a capacitor placed
 * from this table will look something like `PartsDB-Capacitors:CAP-001`
