Add codes for Daikin FWT-GT on Broadlink

[darcato]

This adds IR codes for Daikin FWT-GT fan coil on Broadlink.
It's the same fan coil as #101 . The upstream repo has a similar PR: smartHomeHub#1162 but this is more complete.

I decoded the daikin protocol and used it to generate the codes: https://github.com/darcato/daikin-fwt-gt-ir-code

hello,

it seems that there are repeating commands:

    "low": {
      "fixed": {
        "16": "JgCWAAABOwABPgABPAABPpVRCg0LHwsfCg0LHwoNCg0KDQoNCg0KDQsfCg0KDQoNCx8KDQoNCg0KDQoNCg0KDQoNCg0KDQoNCg0KDQoNCg0KDQoNCg0KDQoNCg0KDQoNCg0KDQoNCg0KDQoNCg0KDQoNCg0LHwsfCg0LHwoNCg0KDQoNCg0LHwoNCg0LHwoNCg0LAAKRlAANBQ==",
        "17": "JgCWAAABOwABPgABPAABPpVRCg0LHwsfCg0LHwoNCg0KDQoNCg0KDQsfCg0KDQoNCx8KDQoNCg0KDQoNCg0KDQoNCg0KDQoNCg0KDQoNCg0KDQoNCg0KDQoNCg0KDQoNCg0KDQoNCg0KDQoNCg0KDQoNCx8LHwsfCg0LHwoNCg0KDQoNCg0LHwoNCx8LHwoNCg0LAAKRlAANBQ==",

This could be replaced by catch-all syntax more elegantly. Would you please consider it? https://github.com/litinoveweedle/SmartIR/blob/master/docs/CODES_SYNTAX.md#climate-operation-commands

Actually those commands are not the same. All the commands are unique, except the on and off which are the same.
