Update the documentation of "prepareReadRecordFile" methods

[andrei-cristea]

CalypsoCardSelection.prepareReadRecordFile(byte sfi, int recordNumber):

• Indicate that the method does not generate an error if the recordNumber does not exist.

CardTransactionManager.prepareReadRecordFile(byte sfi, int recordNumber):

• Indicate that the method does not generate an error if the recordNumber does not exist.
• Indicate that this method must not be used in a secure session while in contact mode (use the other method for this case by providing correct parameters).

CardTransactionManager.prepareReadRecordFile(byte sfi, int firstRecordNumber, int numberOfRecords, int recordSize):

• Indicate that the method does not generate an error if the numberOfRecords or the recordSize are incorrect.
• Indicate that this method must be used with correct parameters in a secure session, otherwise the session will fail when closed.

To keep the API design homogeneous, it is also necessary to modify the signature of all methods that can throw a NoSuchElementException so that they return a null value, empty list, empty map, etc... This will not have a major impact on the version because the behavior of the read methods is more tolerant than before.

The best effort behavior requested must be extended to SFI management, i.e. not generate an error if the file whose SFI is provided does not exist.
