Merge branch 'fix-enum' into next

Fix deprecated enum usage (in Clang 10, arithmetic between different enumeration types is deprecated [-Wdeprecated-anon-enum-enum-conversion])

Fix defect detected by Coverity Scan in Rtcm_Message class (Destination buffer too small: Buffer this->data_ contains 0 characters and is not null-terminated. Copying 6 characters from it overruns this->data_)
