This function is a generic read function. This can be used to read all fields of
the tag. The parameters supported by this function are:
report – List of fields to read from the tag.

this parameter is not specified, the first tag found in the field is read.
pwd (optional) – Indicates the access password required to read a
locked tag (Gen 2 only).
antenna (optional) – Indicates the list of antennas on which the function
executes. If an antenna is not specified, all antennas will be tried until

If the requested fields could not be read, an error is returned.
