In Snowflake dialect `field/100` tokenizes as `Word(field/100)` instead of `Word(field),Div,Number(100)`

Changes in #841 broke division support when there are no whitespace characters around(before) / for Snowflake.

Right now, I don't know how to fix it properly, and I just disabled those chars from the Snowflake dialect in my fork.
