C++ errors in jsoncpp-headers

[UnitedMarsupials]

Trying to build the tool on FreeBSD (both 11.3 and 12.2) with jsoncpp-1.9.4 installed, I get these compilation errors:

mlxarchive_mfa2_builder.cpp:124:38: error: no viable conversion from 'Json::Value::const_iterator' (aka 'Json::ValueConstIterator') to 'Json::ValueIterator'

Seems like a simple fix:
