support 8 kHz sampling rate

[ehussain]

Is your feature request related to a problem? Please describe.
I am using python library to detect voice activity in audio file. but we are going to receive input from stream and it is going to be 8000hz single channel audio. But when I try to test with audio of 8khz sampling rate then library fails because it is not 16000hz rate.

Describe the solution you'd like
Please provide option to set sampling rate for input file.

Additional context
Audio stream will be coming from twilio and we do not have control on the frequency they provide, it is always going to be 8000hz single channel audio. But here we want to use picovoice cobra for activity detection but it is not supported.

you need to upsample the 8kHz audio (yourself) to 16kHz and then pass it to Cobra. Cobra at this time only accepts 16kHz linear PCM. I keep this open to see if we can add it to our roadmap but to be clear we are not working on this at this time.
