S7PLCFW

This is a fork of epics_driver_modules/s7plcFW, with the following adjustments:

• String length is no longer static, but instead read from the SPS directly
• The String offset, now takes the two prefix bytes (max string length, current string length) into account, so you don't have to add 2 to each offset in order for the driver to read the correct string

The driver is documented in the file s7plcFW.html.
