Jacob Kiers b7ec67ed07 Fix SNI header parsing
When a listener is configured to deal with TLS upstreams, we use the SNI
field of the TLS ClientHello message to decide where to send the traffic.

Therefore, a buffer of 1024 bytes was used to temporarily store this
message. However, a TLS ClientHello message can be larger than that, up
to 16K bytes.

So now the first few bytes are read and manually parsed to find out how
long the message is. And then the entire ClientHello message is
retrieved.

So hopefully that will fix the issue causing the ClientHello
determination to fail.

Closes #10

## [Unreleased]
### Fixed
* The ClientHello TLS header is now read in full before it is parsed, solving
an error where there was not enough data to fully read it. In those cases
it was not possible to determine the upstream address and therefore the proxy
would go the the default action instead.
### Changed
* Updated some dependencies to prevent the build from breaking.
## [0.1.9] - 2024-06-22
### Deprecated
The ability to run `l4p` without arguments is now deprecated. Please use
`l4p serve` going forward.
### Added
* Added self update functionality. Just run `l4p update` to use it.
* Now keeping a change log in the `CHANGELOG.md` file.
### Changed
* Updated build pipeline to generate much smaller binaries
