maint: Update minimum go version to 1.19 (#245)

## Which problem is this PR solving?

This project is built with old versions of go, and can no longer take
newer dependencies such as klauspot/compress which require go 1.19 or
later.

This PR updates the minimum go version to 1.19 and runs CI tests in 1.19
-> 1.22

## Short description of the changes
- Update go version in go.mod & run go mod tidy
- Update CircleCI tested go versions to test 1.19 through 1.22
