Review Comment:
Would it may be possible to inherit from the ByteInputCallback instead of
composition? It may shorten some [train
wrecks](https://devcards.io/train-wreck) like
`http_client_->getReadCallback()->getPtr()->getSize()`. Same for
HTTPReadCallback

These lambdas seem to be unused, am I missing something here?

Could the mutex be removed and `atomic<size_t> pos;` used instead? Same for
