[Feature]: Framed Slope Prism Corner / Framed Half Slope Prism Corner

[AbusRenn]

Describe the feature

Framed Slope Prism Corner: there is no 1/4 block size prism corner so you can not join a vertically placed "framed slope edge" with a vertically placed "framed large/small inner corner slope panel"

. Framed Half Slope Prism Corner: there is also no 1/8 block size prism corner making it so you can not join vertically placed "framed slope edge" and a horizontally placed "framed slope edge"
