Software request: Level converter

[Defrago]

There is considerable amount of prerelease, demo and regional versions of levels, including other platforms ones which currently can't be played with TR2Main project. OpenLara project by @XProger has implementations of some of the formats described above. After Discord discussion with @rr- we concluded that there would be better to create a separate level converter rather than expand TRXMain projects codebase with additional versions of levels reading. So I propose to create a converter for the levels from PS1, Demo and Prerelease formats to T2M PC ones.

As for demos, there should be an option to disable level end trigger to allow more exploration.

I created similar request for TR1-related levels on T1M project GH page so whoever decides to start such converter might consider to unite his efforts with other TRXMain developers to support their TR(1, 2 ,3, 4, 5) levels as well.

Some work been done towards it as far as I know
