include coil info parameter

[raamana]

we need to add coil info parameter(s) for protocol compliance checks.

Getting info on this is not easy and varies across vendors unfortunately (see here), but for siemens, it seems to be at 0x0051, 0x100F, so it should be easy for us to add.

some example codes/variations for coil string:

32 ch: HEA; HEP
64 ch: HC1-7; HC1-7; NC1,2
20 ch: HE1-4

relevant BIDS meta data tag: ReceiveCoilActiveElements

Added DICOM tag in config file

[raamana]

looks like we need to properly decode the coil string in dicom header, and implement the equality condition in a more detailed manner (beyond simple string match)

it would be ideal to make it work for all body organs, not just brain:
