The returned promise resolves to an object, containing:

* `serverName` - The server name requested in the client hello (or undefined if SNI was not used)
* `alpnProtocols` - A array of ALPN protcol names requested in the client hello (or undefined if ALPN was not used)
* `alpnProtocols` - An array of ALPN protocol names requested in the client hello (or undefined if ALPN was not used)
* `fingerprintData` - An array containing the raw components used for JA3 TLS fingerprinting:
1. The TLS version number as a Uint16 (771 for TLS 1.2+)
2. An array of cipher ids (excluding GREASE)

* `getTlsFingerprintAsJa4` - Reads from a stream, just like `readTlsClientHello` above, but returns a promise for the JA4 hash string, e.g. `t13d591000_a33745022dd6_1f22a2ca17c4`, instead of the raw hello components.
* `readTlsClientHello(stream)` - Reads the entire hello (see above). In the returned object, you can read the raw data components used for JA3 fingerprinting from the `fingerprintData` property.
* `calculateJa3FromFingerprintData(data)` - Takes raw TLS fingerprint data, and returns the corresponding JA3 hash.
* `calculateJa4FromHelloData(data)` - Takes the full hello data, including the serverName, alpnProtocols & fingerprinting parameters returned by `readTlsClientHello`, and returns the corresponding JA4 hash, eg. `t13d591000_a33745022dd6_1f22a2ca17c4`.
