Missing runtime dependency "requests" in 0.2.7

[hoechenberger]

Hello! I'm co-maintaining the neurokit2 package on coda-forge. When trying to test version 0.2.7 (a simple import test), it appeared that a new runtime dependency on requests has been introduced, but it's not explicitly specified in the project dependencies. The requests dependency often goes unnoticed as most Python installations deploy requests by default. Could you please explicitly add this package to the list of dependences? Thanks!
