Description

I tried setting max_fragment_size_bytes to 0x10000 in settings_example, but got an error from DAQInterface complaining about base-10. It might be nice to support setting some parameters in hex...

JCF: resolve Eric's Issue #21496 by allowing hexadecimal values for the max_fragment_size_bytes parameter in the DAQInterface settings file

Instead of a decimal value (e.g., 1024000) a hexadecimal value such as
0xfa000 or 0xFA000 can be used. For good measure / consistency, extend
this feature to the value used for the max_fragment_size_bytes FHiCL
parameter when advanced memory usage is selected.

With commit cfd9044873b6a742d8427feb1da20f32eac1ffd1 on the develop branch, this request is satisfied. Now, values assigned to max_fragment_size_bytes which begin with an "0x" are understood by DAQInterface to be hex values. E.g., 

max_fragment_size_bytes: 0xfa000

or 
max_fragment_size_bytes: 0xFA000

are equivalent to 
max_fragment_size_bytes: 1024000

...as I've confirmed with runs 1754 (1024000), 1755 (0xfa000) and 1759 (0xFA000) on mu2edaq01 (see mu2edaq01:/home/jcfree/run_records for details).

Note that with this commit, this hexadecimal support extends to the values of max_fragment_size_bytes in individual boardreader FHiCL documents when advanced memory usage is selected.
