Output to parallel elegant format (binary)

[nneveu]

Feature request: add an option that allows elegant_write() to dump a binary format that works in parallel elegant
Something along the lines of what the pysdds module does:

import sdds
pysdds = sdds.SDDS(0)
pysdds.load(outfile)
pysdds.mode = pysdds.SDDS_BINARY #to convert from ASCII to BINARY, need binary for pelegant
pysdds.save(outfile)

sdds data module is needed from elegant page:

The sdds Python module is now available on conda-forge as part of the elegant package. So perhaps we could address this request at some point (@ChristopherMayes?)
