Change default behavior of writeReg to not print to terminal on every call

Brief summary of issue

The writeReg function in the python API makes what I feel are undesired print statements to terminal. I would suggest that this is changed to only make print statements when a debugging flag was provided.

Types of issue

[ ] Bug report (report an issue with the code)
[x] Feature request (request for change which adds functionality)

Expected Behavior

The code would only print the write attempt to terminal if a debug flag existed and debug=True was passed at runtime.

e.g.

Changing the function declaration from:

https://github.com/cms-gem-daq-project/reg_utils/blob/2879f89d67994212d0d71f0616224195edc79ea9/python/reg_interface/common/reg_base_ops.py#L99

to:

def writeReg(reg, value, debug=False):

And changing line 104:

https://github.com/cms-gem-daq-project/reg_utils/blob/2879f89d67994212d0d71f0616224195edc79ea9/python/reg_interface/common/reg_base_ops.py#L103-L104

to:

    if debug:
        print "Initial value to write: %s, register %s"% (value,reg.name)

Current Behavior

Shown in lines 99-128:

https://github.com/cms-gem-daq-project/reg_utils/blob/2879f89d67994212d0d71f0616224195edc79ea9/python/reg_interface/common/reg_base_ops.py#L99-L128

Presently the code will always print the write attempt to terminal.

Context (for feature requests)

Clutters terminal output when write transactions are performed, e.g.:
