Corrected PyBind Enum Names

[aeoranday]

This closes issue #11. Accessing the enums in python was tested as follows:

import trgdataformats
print(trgdataformats.TriggerActivityData.Algorithm.kPrescale.name)   # kPrescale
print(trgdataformats.TriggerActivityData.Algorithm.kPrescale.value)  # 2
print(trgdataformats.TriggerActivityData.Type.kTPC.name)   # kTPC
print(trgdataformats.TriggerActivityData.Type.kTPC.value)  # 1

This was repeated for trgdataformats.TriggerPrimitive and trgdataformats.TriggerCandidateData and various other types and algorithms. I also tested the functionality in trgtools and found that everything continued to work as expected.

If I use the original (patch/fddaq-v4.4.x) branch, then the enum value appears for only one of the class types, and that without any qualification. E.g., if I do

from trgdataformats import *
kChannelAdjacency

then I get <TriggerCandidateData::Algorithm.kChannelAdjacency: 12>...but have no way to get the enum of the same name for TriggerActivityData, thanks to the complications caused by the double colon.

On the other hand, if I use Alex's branch, I can do:

from trgdataformats import *
TriggerCandidateData.Algorithm.kChannelAdjacency

and get <Algorithm.kChannelAdjacency: 12>, but also TriggerActivityData.Algorithm.kChannelAdjacency and get <Algorithm.kChannelAdjacency: 10>.
