Module parsing

Helper functions that convert common C types (primarily UTF-8 encoded char * pointers) into the Rust data structures used throughout PoseiTrader.

The conversions are opinionated:

• JSON is used as the interchange format for complex structures.
• ustr::Ustr is preferred over String where possible for its performance benefits.

All functions are #[must_use] and, unless otherwise noted, assume that the input pointer is non-null and points to a valid, null-terminated UTF-8 string.
