Use a pool for connections

[vixez]

I needed a way to make requests run in a sequence, not parallel.
This is more explained in the issue here.

The changes here introduce a Pool, so you can limit the amount of active requests by setting maxActiveRequests.
By default this is 32, feel free to change this or skip the pool altogether if not set.

This code for example will make sure all requests, including for example retrieving a token in a RetryPolicy will run one by one.

return InterceptedClient.build(
    interceptors: [
        ApiLoggingInterceptor(),
        AuthenticationInterceptor(),
    ],
    requestTimeout: HTTP_TIMEOUT,
    retryPolicy: NewTokenRetryPolicy(),
    maxActiveRequests: 1,
);

To get a token in RetryPolicy I use a seperate InterceptedClient which is also limited to one request.

Hey, thanks for the contribution, I'll take a closer look soon, but in the meantime:

• It would be nice to have this feature be optional, otherwise, it might interfere with current functionalities. Maybe it can be an approach like the one used by Felix Angelov in the bloc_concurrency package, but just some thoughts about it.
• Maybe it would also be a good idea to update the README on this and add examples. This has been something that other users of the package have requested.
