Optimize chars in natural integer numbers with HEX values (special sign upper "I" letter for hexadecimals instead of lower "i" letter for integer) #21

Example of generic IoText data protocol row:

t|3900267526042,d|meter_01,m|distance_mm=i:12345

after DEC to HEX conversion, we have -1 byte per one record (data field) in this example

t|3900267526042,d|meter_01,m|distance_mm=I:3039

For this operation it will be good to use instead of a lower i letter in the record, an upper case I letter - it will be an identifier for HEX integer values.

It will be an important aspect for values as bytes optimization when we have _0 or _00 data records in one row. We will have _0 or _00 less bytes in one row, which is not too bad.

"I" upper letter is reserved for this feature #24 - list of values in one metric
