Description:

This PR implements the between operator in segments for numeric fields.

Steps to test this PR:

1. Open this PR on Gitpod or pull down for testing locally (see docs on testing PRs here)
2. Create a Custom Object People/Person and add a number field "Family Members".
3. Create 3 custom items from this object; 'A', 'B' and 'C' and assign them 3, 7 and 12 family members respectively.
4. Create 3 contacts 'A', 'B' and 'C' and link them to People 'A', 'B' and 'C' respectively.
5. Create a new segment "Family Members Between Segment" and add People:Family Members as filter field.
6. Choose "between" operator. Two input fields should appear.

7. Enter 5 and 10 in the "From" and "To" boxes respectively and save the segment.
8. Wait for the segment to build.
9. Verify that only contact B (the one with 7 family members) is a member of the segment.
10. Additionally try saving the segment leaving either of the two input fields blank, or entering non integer values. You should see an error message.

11. Create another segment, "Family Members Not Between Segment", with same configurations as the previous one. Except this time choose "not between" operator.

12. Wait for the segment to build and verify that this time the contacts with 3 and 12 family members are members of the segment.

This is not working in the beta version. @aarohiprasad is having some issues with the merging. She will fix it.
