Change val MapEntry from float to double

[pennam]

Using this sketch assigning from the dashboard the vale of 1609459800 to time2 variable it will result to print 1609459840.

Looking at CborMapData class, the 1609459800 value is stored into a float variable and its hexadecimal rapresentation will be 0x4EBFDCD1; going back to int we will get 1609459840.

Storing the value in a double variable will avoid conversion errors.

I've used this web converters to check conversion error:

• https://babbage.cs.qc.cuny.edu/ieee-754.old/32bit.html
