util: Improvements of string helpers

Improvements include:
- test cases for every string helper
- a new `printHex` helper to output hex conversion directly to std::ostream
- new `toHex` and `printHex` helpers that accept Buffer as input parameter
- a new `fromHex` helper to convert the supplied string to shared_ptr<const Buffer>
- replaced uses of CryptoPP routines with `toHex` and `fromHex` helpers where applicable
