TLS cipher hexadecimal logging

[petecooper]

Hello.

Per the documentation:

> $ssl_cipher
> returns the name of the cipher used for an established SSL connection.

This means `$ssl_cipher` returns e.g `TLS_CHACHA20_POLY1305_SHA256`.
Is it possible to return the corresponding hex value e.g. `0x1303` instead?

Thank you, and best wishes.
