This command is used to re-request a specific fragment returned by a MultiDataCommand from the inverter.

Derives from SingleDataCommand. Has a fixed length of 10 bytes.

Command structure:
* ID: fixed identifier and everytime 0x15
* Idx: the counter of sequencial packages to send. Currently it's only 0x80
  because all request requests only consist of one package.
* Frm: is set to the fragment id to re-request. "Or" operation with 0x80 is applied to the frame.
