Support -1e11 to 1e11 for numeric matching

[baldawar]

What is your idea?

Ruler supports matching for up to -5e9 to 5e9. Clients may want to match higher ranges. So far 1e11 is the most I've heard, so comfortable with building support for it, but we should change the code to enable future support for bigger ranges as they're probably not far away.

Would you be willing to make the change?

No (don't have bandwidth to look into this yet)

Additional context

• Today we normalize all numbers to 14 hex digits, every new precision has implications in memory. There's a slight CPU hit as well as we normalize the numbers.
• As part of the normalization process, we do some coversions between float to longs. These can get inaccurate when larger numbers are involved.
