Summary:
This is just a little script that will run a search and print out the timings
for each of the searches that ivy will preform.
For example running
```
nvim -l ./scripts/integration.lua /path/to/repo test 2> /dev/null
```
will output
```
t 0.074737
te 0.016494
tes 0.018898
test 0.017214
```
Test Plan:
Does not really require testing, this is a little helper script for
development. If it does not work on another machine then we can cross that
bridge when we come to it.
