Update version and encapsulate class fields in IEXCloudClient

The pom.xml version was updated from 1.13.0-SNAPSHOT to 2.0.0-SNAPSHOT. This signifies substantial changes or upgrades in the application.

In the IEXCloudClient.java, class field variables (reference, companyData, historicalData) were changed from public to private to adhere to good Object-Oriented Programming practices. Public accessors (fetchReferenceData, fetchCompanyData, fetchHistoricalData) were also added for each field to safely retrieve their values.
