@brief reads a UBJSON string
This function first reads starting bytes to determine the expected
string length and then copies this number of bytes into a string.
This function is either called after reading the 'S' byte explicitly
indicating a string, or in case of an object key where the 'S' byte can be
left out.

input (true, default) or whether the last read
