Implement Encrypt Ballot (#35)

* ✨ Encrypt Ballot Endpoint

Encrypt a single ballot via endpoint. 
Provide new ways to pass in the ElectionMap and ElectionGuardConnfig to remove the restrictions from coming into the pathway from different directions. This also allows for a different direction for the current count which now can be passed in OR just simply incremented.

* Rework the mock EncryptBallot API

add support for loading configuration at runtime from a relative path

* Feature/modify controller endpoint (#34)

* Change route from /election to /electionguard

* check the call context for data directory

if failed check the parent folder

* Implement Encrypt Ballot

Rework API's for data consistency.  Update postman collection for new requests

* Fix typo. disable request size limits

* try catch on all methods.  Validate RecordBallots input data

when RecordBallots is called, de-dupe the ballots, taking the first & verify the cast/spoiled count matches the de-duplicated dataset count.

* update tallies

* add example curl commands

* use last encrypted ballot
