chore: deprecate methods in symmetryutilities.py

[stevenhua0320]

@sbillinge ready to review. Note that I forgot to add the deprecation message for the readStr in the PDFFitStructure class in the past PR, so I add it here. Also note that for symmetryutilities.py there are a lot of new-written functions that created with no tests, I would consider how we handle with it in the next PR.

I suggest that we are consistent and abbreviate lattice to latt everywhere and parameter to parm or maybe better, param. Either way I think it is quite important that we use the same abbreviation for things everywhere they appear.

Got it, I have made all lat to latt and parameter to parms since we have declared the name for parameter in the previous PR to be consistent. Furthermore, I realized I'm dumb to forget to edit the name of the method inside the argument, it should be readStr and read_structure here. See the latest commit.
