Different Double Slabs

This release is tested with all versions 1.20.0 and up!*

*The only caveat is that the resource pack won't automatically have support for any new slabs added after 1.21.0, so message me on Discord reminding me to add them! (@owehttamy)

Changes:

• Added full support for all slabs in Charm

Thanks @peow. on Discord!

• Added full support for all slabs in Clutter

Thanks @peow. on Discord!

• Added full support for all slabs in Nature's Spirit

Thanks @peow. on Discord!

• Added full support for all slabs in Philip's Ruins

Thanks @peow. on Discord!

• Added full support for all slabs in Twigs

Thanks @peow. on Discord!

• Renamed all parents to shorter, more accurate names
• Added all_flipped and column_flipped parents

Rotates the textures 180°

• Added column_inverse parent

Simply swaps the side and end textures

• Added column_row/* parent

Turns the column block on its side, depending on cardinal direction

• Added column_mirror parent
• Added column_stacked parent
• Subsequently moved all existing "stacked" variants to "column_stacked" parent, dramatically decreasing sizes
• Fixed culling and UV on column_stacked model
• Properly changed rotation of all_90 and column_90 parents to be all 90° rotations, as some were 270°
• Removed parents from parents, since they're unneeded and unused
• Created single-slab variants for column_stacked parent
• Added culling to single-slab parent variants
• Added support for particles in parents

Whoops, I should've done that in 1.0

• Removed all unnecessary texture calls for particles in individual files
• Removed unnecessary "minecraft:" clarifications
• Changed stoneexpansion:cut_mud_slab parent from column_90 to column_stacked
• Fixed all column parents to only utilize one cube
• Moved "all" parent variants to "all" folder and shrink names
• Moved "column" parent variants to "column" folder and shrink names
• Renamed all model folders to be singular form
• Renamed all models in model folders to just be model type instead of repeating block name
• Removed the modding tutorial because it's drastically outdated now, and I intend to transform it into a YouTube video later instead

I can't be bothered to make a temporary new one
