add IncrBy/DecrBy function for integer

[chuwt]

Increments or decrements the number stored at key. Very useful for add/sub integer like balance.

any reason for a specific function for this when you can just do

Table.setCount(Table.getCount() + 1)

[chuwt]

Yes, but it sometimes becomes duplicate when there are too many keys like:

Table.setCount(key1, key2, key3, Table.getCount(key1, key2, key3) + 1)
# would be good if we support incrBy
Table.incrByCount(key1, key2, key3, 1)

Anyway, just an advanced feature.

Appreciate the feedback, but we don't have plans to expand the table API surface area in this way.
