Invalid: Using a "-" to describe a gcm name and using that description as a table

Problem: The gcm names in climR have "-" which is a special character. On line 158 climateCastor attempts to name a SQLite table using this special character which is invalid.

Solution: Naming of the tables in castor should be special character safe

Start at line 158 in climateCastor, where a gcm name is used to create a SQLite table, and reproduce the failure with a name containing a hyphen. Done means gcm names containing special characters no longer produce an invalid table name; add or update a regression test if the project has coverage for this path.
