feature: move the QASM export to dedicated module

**Describe the feature you'd like**
I think it would be a good idea to move the QASM export(and import) to a dedicated seprated module of its own or a sub module of a bigger exporter module which would support multiple types of standardized exports.

**How would this feature be used? Please describe.**
The function can stay as it is but the internal working can be offloaded to a seprate exporter module, allowing for a much cleaner code base
