large ipv6 ranges lead to an error

[hojerst]

NetBox version

v3.0.2

Python version

3.9

Steps to Reproduce

1. try to create an ip range for 1:2:3:4::/64 to 1:2:3:4::ffff:ffff/64

I assume, that the size calculation leads to an error, as this doesn't fit to an int32

Expected Behavior

ip range is created

Observed Behavior

Server Error

The range size is currently stored as a signed integer, with a maximum value of 2^32-1, or essentially half the size of the entire IPv4 space. While perhaps it was an omission to not document the maximum supported range, I don't know that it makes sense to raise this any higher. When we talk of IP ranges, we're typically referencing magnitudes in the hundreds or thousands of individual addresses, not millions. Open to other opinions.
