Stream crystal hits to "UC" instead of "UH" in ROA output

[fhagemann]

Currently, when running simulations with the EM massmodels, the current implementation of the DEE results in MStripHits and MCrystalHits both being saved to UH to the ROA file. This messes up parsing these ROA files, because the rows for crystal hits have fewer entries:

I was wondering whether UH here is actually correct, or whether it should be exclusively reserved for MStripHits.
It looks like MShieldCrystalHits for example are saved to UC instead of UH:

nuclearizer/src/MShieldCrystalHit.cxx

Lines 159 to 163 in 79ac091

	void MShieldCrystalHit::StreamRoa(ostream& S, bool WithADC, bool WithEnergy, bool WithFlags, bool WithOrigins)
	{
	//! Stream the content in MEGAlib's evta format
	S<<"UC "

whereas MCrystalHits are saved to UH:

nuclearizer/src/MCrystalHit.cxx

Lines 159 to 163 in 79ac091

	void MCrystalHit::StreamRoa(ostream& S, bool WithADC, bool WithEnergy, bool WithFlags, bool WithOrigins)
	{
	//! Stream the content in MEGAlib's evta format
	S<<"UH "

Writing MCrystalHits also to UC instead of UH would prevent my current scripts from failing in case ACS hits are present in the simulations 😇

Let me think about this - the roa / UH format is the universal format to get stuff into melinator.

The dat format was originally intended to just store all the information which was in the class.

we just stopped updating it at some point in time.
