Basic RDM Responder Support is Here!

This version of esp_dmx bring basic support for RDM responders! The parameters which are supported include:

• Supported Parameters
• Discovery Unique Branch
• Discovery Mute
• Discovery Un-mute
• Device Info
• Software Version Label
• Identify Device
• DMX Start Address

Currently, the RDM responder does not support queuing messages, nor does it support ACK_OVERFLOW responses. Support for these features and more parameter support will be coming soon!

Because previous versions of esp_dmx were in beta, this release contains some breaking changes from previous versions. Moving forward, semantic versioning will be followed more closely (i.e., breaking changes will only occur between major versions).
