Pref for socket timeout

[pyamsoft]

See related #349

To save memory and free up coroutines, we dropped the hard coded timeout to 10 seconds.

However, some websites do in fact take longer to read/write the socket, namely in 349 where the website takes almost 2 minutes.

Like the power balance, allow users to configure Socket timeout. Recommend power balance unlimited for fastest response and lowest connection latency.

3 sec - note that this uses the least memory, lowest latency, but may be TOO fast. Unlimited power balance recommended.
10 sec - default, balance between memory and connection allowance, compat with most well behaved websites
1 min - use more memory, higher latency, compatibility with many websites
5 min - lots of mem, lots of latency in some cases, most websites will work
Unlimited - yolo dolo I hope the website you are connecting to is well behaved
