Bug: False positive data detection in `infer-schema`

[aaronsteers]

I came here to report a bug and start working on a PR but I see there may already be two open PRs that relate to this issue.

The issue is that integers and numerics are sometimes/often inferred to be date-time data types, which causes issues downstream if the resulting schema is not manually overriden.

See #16 for what appears to be a valid fix.
