Remove use of named groups in regexp

[uvjustin]

Proposed change

We previously used named capture groups in a regexp in ha-hls-player to be more clear about what the regexp is doing. Unfortunately named capture groups were not supported in firefox versions < 78. This PR reverts to using regular capture groups instead of named ones.
