pldmtool: Add GetStateEffecterStates command

Add GetStateEffecterStates command in pldmtool.
Used to get state effecter current and pending states
by supplying an effecter ID.

Tested:
```
root@bmc:~# pldmtool platform GetStateEffecterStates -h
get the state effecter states
Usage: pldmtool platform GetStateEffecterStates [OPTIONS]

Options:
  -h,--help                   Print this help message and exit
  -m,--mctp_eid UINT          MCTP endpoint ID
  -v,--verbose
  -n,--retry-count UINT       Number of retry when PLDM request message is failed
  -i,--effecter_id UINT REQUIRED
                              Effecter ID that is used to identify and access the effecter
root@bmc:~# pldmtool platform GetStateEffecterStates -m 9 -i 348
{
    "compositeEffecterCount": 1,
    "effecterOpState[0])": "Effecter Enabled No Update Pending",
    "pendingState[0]": 1,
    "presentState[0]": 1
}
```
