This commit adds support for a second supported hash (currently set to the 4.0-beta1 tag). When this hash is detected, the relevant changes are applied. This allows to start using v4 features (e.g. BLE with Nimble), and also start doing testing, while still supporting the original, stable, v3.3 IDF. Note: this feature is experimental, not well tested, and network.LAN and network.PPP are currently unsupported.
