- Fixed a segfault when using a user-defined conversion function between compound datatypes

During type info initialization for compound datatype conversion, the library checked if the
datatypes are subsets of one another in order to perform special conversion handling.
This check uses information that is only defined if a library conversion function is in use.
The library now skips this check for user-defined conversion functions.

Fixes Github issue #3840
