Updated the filter endpoint to not allow for the output sampling period to be none. If it is left empty an error code wil prompt you to provide an appropriate sampling period. This involved adding some logic to a few of the test and a couple logger warming that would skip trying to determine wehter the number of smaple reqeusted ignores the sample request limit.

Removed union method from FilterApiQuery and Filter.py, I also added a negatvie test to filter_test to account check that an innapropriate float would cause and error. I also removed the asyn functions from data_test.py because they were being skipped in the testing pipeline. I made them regular function and they are now passing.

Reverted test to allow strings for specifc parmaters. I believe I grabbed an old version of DataAPIQuery that caused the test to fail before. Things should now be up to date.
