Explaining S1 changes/updates:

@xC0uNt3r7hr34t Noted in #129 that there were unnecessary changes made to the pagination within S1, which should never have been altered. To address this bug and maintain limits in accordance with the S1 console and documentation, the pagination limit has been reset to 1000, which was the setting prior to the limit feature being introduced into Surveyor. The limits for Deep Visibility and Power Query have been maintained at 20000 and 1000, respectively. These values are updated in the request parameters, which is the only value that should have been changed.

Testing passed for in and out of bounds ranges for each mode.
