getShotDB does not include shots stored in paths with shot digit wildcards

Shot digit wildcards in path specifications like ~a are not processed correctly by getShotDB. ~t does get processed correctly. The code does not look like it makes any attempt to process it.

Line 359 in 6f906d0

def getShotDB(expt, path=None, lower=None, upper=None):

The drop down in jTraverser2 also ignores these wildcard paths.

The combinatorics on ~a through ~j with ten possible digits are enormous. I'm not sure that this function could ever be performant and return a complete result, but I hope I am wrong because "what shots exists" is a very reasonable question to ask. Minimally I think the limitation should be documented, perhaps even an automatic warning if getShotDB finds wildcards in the EXPT_path.

We could return fairly complete results except for the syntax that allows you to call a function.  However we will not be able to do this in a performant way.  It seems that we could try to use a linux `find` command either locally or remotely, but formulating that command for any string that you can have in the tree path may be tough.  In addition we would need a new mdsip `entry point`, probably a `.fun` for remote find commands. We have discussed in the past the desire / need for a database of shots, and an API to go with it. I think we can add solving this to our longer term projects list.
