v1.18.2

## Fixes and improvements

RTSP

* fix compatibility with Verint.Vms.MediaGateway (https://github.com/bluenviron/mediamtx/issues/5292) (https://github.com/bluenviron/gortsplib/issues/1061)
* fix crash when stream is closing (https://github.com/bluenviron/gortsplib/issues/1062) when ServerStream.Close() is called, stream readers might have their setuppedTransport set to nil, causing the server to crash. Prevent this.
* fix race condition when tearing down connection (https://github.com/bluenviron/gortsplib/issues/1063) ServerConn.session was not properly protected.
* fix leak in case of failure during multicast initialization (https://github.com/bluenviron/gortsplib/issues/1064)

RTMP

* prevent nil / unconfigured tracks from appearing (https://github.com/bluenviron/gortmplib/issues/66) (https://github.com/bluenviron/mediamtx/issues/5724) (https://github.com/bluenviron/mediamtx/issues/5729)

HLS

* fix error 500 caused by in-stream params (https://github.com/bluenviron/gohlslib/issues/355) (https://github.com/bluenviron/mediamtx/issues/5728) (https://github.com/bluenviron/mediamtx/issues/5745) PR https://github.com/bluenviron/gohlslib/issues/344 caused a regression. Many codecs (AV1, H264, H265, VP9) use in-stream parameters, that were not taken into consideration anymore when generating init.mp4 and playlists. This has been solved.

WebRTC

* fix checking POST responses (https://github.com/bluenviron/mediamtx/issues/5758)
* support interacting with servers with no trickle ICE (https://github.com/bluenviron/mediamtx/issues/5273) (https://github.com/bluenviron/mediamtx/issues/5757)
* support WHIP ICE restarts (https://github.com/bluenviron/mediamtx/issues/5183) (https://github.com/bluenviron/mediamtx/issues/5770)

RPI Camera

* support changing text overlay dynamically (https://github.com/bluenviron/mediamtx/issues/5270) (https://github.com/bluenviron/mediamtx/issues/5748)

## Security

Binaries are compiled from source code by the [Release workflow](https://github.com/bluenviron/mediamtx/actions/workflows/release.yml), which is a fully-visible process that prevents any change or external interference in produced artifacts.

Checksums of binaries are also published in a public blockchain by using [GitHub Attestations](https://docs.github.com/en/actions/concepts/security/artifact-attestations), and they can be verified by running:

```
ls mediamtx_* | xargs -L1 gh attestation verify --repo bluenviron/mediamtx
```

You can verify checksums of binaries by downloading `checksums.sha256` and running:

```
cat checksums.sha256 | grep "$(ls mediamtx_*)" | sha256sum --check
```
