Using mudata.concat() converts the keys in ModDict from generic Python strings to Numpy strings, causing an error to be thrown when using MuData.write(). The purpose of this pull request is to prevent this error by converting the keys in the ModDict of the returned MuData object back to generic Python strings, which can be written to .h5mu without issue.
