Support hexadecimal literals

[turbanoff]

It would be nice to have support for hex literals. Especially useful for query with address conditions

select *
from "java.lang.Object[]" o
where getAddress(o.this) = 0xe8a675b8

Please note, that right now this can be achieved by using 'toLong' function:

select *
from "java.lang.Object[]" o
where getAddress(o.this) = toLong('0xe8a675b8')
