A JSON message can now be received on:
'vesper/DEV_ID/control/addSchedule"
Each message, must hold a "file" and "data".
The file is the month's name in 3 letter mode (eg jan, feb, mar)
The data is an entry for each day of the month.
Each day can be an array containing multiple items.
The setting is saved on a file in:
/settings/relayTimings.json
Then during bootup, it's read and restored.
Settings can be set via MQTT command on Topic:
vesoer/*dev-id*/control/settings/relayTimers
using a json format.
{ "b1":50, b2...}
where b1 is Bell 1, b2 Bell 2, etc..
A new Melody Struct was added containing the melody's main attributes.
The MQTT Topic Subscriptions were updated to a more proper format.
Also added DEV_ID that corresponds to the device's ID or Serial Number.
Chnaged the Deserialization function to actually adjust the MelodyStruct's attributes.
Added basic play/stop functionality.
