CLI `import` does not respect limits

**Describe the bug**
- no `limit` option works for the `import` CLI
- limits are capped at 100

**To Reproduce**
Run `builder import -o foo -l 1` and see `Variable "$v1" got invalid value "1" at "v1.limit"; Float cannot represent non numeric value: "1"`.

**Expected behavior**
- i expect the `-l` option to parse the number for the argument
- i expect to be able to export all my data (greater than 100 entries per model)

**Additional comments**
We have been rolling our own exporter for the purposes of scheduled backups, as well as running "migrations" on existing data. But we'd prefer to use this tool.
