BDE 4.34.0 Release Highlights

`balxml::MiniReader` Now Supports the UTF-8 Byte Order Mark (BOM)

This release adds logic to balxml::MiniReader to recognize and allow the UTF-8 byte order mark sequence (BOM). Both the big- and little-endian UTF-16 and UTF-32 BOMs are also recognized, and now result in an error.

`baljsn_datamutil`: Behavioral Change When Writing `e_INTEGER64` Values

baljsn_datumutil has been changed so that when writing a bdld::Datum having type e_INTEGER64 to a JSON number, the value is written directly and in full, omitting previous the cast to double. Translation in the other direction is unchanged.
