To remain in compatibility with MySQL, added ability to interpret decimal arguments as datetime strings for temporal functions.
Fixed YEAR(), MONTH(), DAYOFMONTH(), DAYOFYEAR(), HOUR(), MINUTE(), SECOND(), and MICROSECOND() to accept decimal parameters and interpret them the same way as MySQL.
Fixed an issue with the TemporalFormat::matches() method which was incorrectly assuming all microsecond arguments were specified as 6 digits. Added power of 10 multiplier to usecond calculation. This fixes issues with failures in type_date and func_sapdb test cases.
