Immersive Portals - Make it compatible 1.3.0

The mod was called "IP x Sable x Voxy" until this release.

Distant Horizons inside portal views

• Distant Horizons' far (LOD) terrain now renders inside portal views: each portal pass draws the destination's LODs from the portal camera. Before, the far side of a portal ended at the loaded chunks. Immersive Portals is switched to its framebuffer (compatibility) portal renderer for it, as the Voxy patch already did. Not used while a shaderpack is active. Tested with portals inside one dimension; portals into another dimension load that dimension's LODs as they are needed and are new, so report what you see.
• Option distantHorizonsInPortalViews in config/micimmptl-common.toml, on by default. Works with Distant Horizons' own classes by name, so a Distant Horizons whose internals differ leaves the patch dormant instead of crashing.

Sable patch moved out

• The Immersive Portals x Sable patch (vehicles through portals, mounted portals, balloon lift, the physics staff, Veil clip planes) now lives in Sable - Make it compatible 1.3.0. Install that mod next to this one to keep vehicles and portals working together; this jar is a third of its old size. The options straddleSideArms, hullLightPerPortalSide and balloonLiftContinuity left micimmptl-common.toml with it.
