Modbus Data_Type = "BCD"

Use Case

Hi.
A Modbus device delivers some Registers as data_type = BCD.
For example the "Date & Time" information via 3 Bytes (24bit) as BCD.

So far, I did not find a way to decode these registers :-(

Question is:
Is there a way to decode BCD coded registers?
or
could this become a new feature??

Thanks for your the brillliant "Telegraf"
Cheers

Expected behavior

Decode for example:
Read 3-bytes and assign 4-bits per digit
and
assign 2 digits to the 1st number ( e.g.: the day)
assign 2 digits to the 2nd number (e.g.: the month)
assign 2 digits to the 3rd number ( e.g. 2 digit year)
etc.

Actual behavior

??

This datatype does not exist yet, someone needs to implement it. PRs appreciated!
