Request: corner pieces for half slope

[SamMatzko]

There are many kinds of slopes in moreblocks, however there are two that are missing that create annoying inconsistencies in builds. There are no corner pieces for the half slope and half slope raised nodes:

For example, I used the half slope and raised half slope nodes to create a steep roof atop a bell tower. But these corners are empty, because there are no slope nodes that fit in the spots:

It would be nice to have the two slope corner pieces that fit in those spots so that steep roofs like this are more smooth.
