Reasoner-transpiler

added the ability to set the biolink model to a specific version with an env var

- switched from bmt-lite to bmt v1.2.1 (biolink model 4.1.4)
- updated tests according to new biolink model
- improved qualifier query validation with bmt, throw exception if qualifier is not valid or qualifier value does not exist in an enum

updated to new bmt-lite version (with biolink model v3.6.0),
now allowing for symmetric predicates to be queried for even if they are not 'canonical',
changing qnode_id to query_id in cypher returns

- removed checks for primary knowledge source, this should happen outside of the transpiler
- now checking for subclass and superclass predicates in queries and preventing subclass inference for nodes on those edges
- added InvalidPredicateError exception, throw when a predicate unknown to the biolink model is encountered
