Fix Spectra's relationships

[HebaruSan]

Problems

A number of issues have arisen with respect to Spectra:

• It depends on EVE, Scatterer, TextureReplacer, and Kopernicus, but in principle a user could choose to install without those other mods and still get some value out of it
• It provides configs for EVE and Scatterer, but this is not reflected in the metadata
• It has a functional conflict with GreenSkullRevived (both attempt to install an EVA visor for TextureReplacer), but this is not discovered until you try to install both and get an error message

• [Bug] Mod conflict (Spectra and Green Skull Revived) #7662 (comment)

Changes

• Now EVE, Scatterer, TextureReplacer, and Kopernicus are recommended instead of depends
• Now Spectra is marked as providing and conflicting with EnvironmentalVisualEnhancements-Config, Scatterer-config, and Scatterer-sunflare
• Now GreenSkullRevived is explicitly a conflict

Fixes #7662.

Greetings! I can confirm that these fixes are perfect. Thanks for bringing it to my attention that Spectra's CKAN files are screwed up
