Baritone is struggling to start building Very large Schematics on both internal and Schemitica ends

## Some information
Operating system: windows 10
Java version: 8
Minecraft version: 1.12.2
Baritone version: 1.2.15
Other mods (if used):
Shematica (others I dont think are relivent for this issue

## Exception, error or logs
Not part of issue

Ill just get to the point, I noticed that when it uses #Build and #schematica command when set to work with a mega build project that it struggles to even start building

## How to reproduce
Run the command with the internal schematic loading system or use Schematica while set on Layer mode

## Modified settings
Layer mode was set to true

## Final checklist
- [x] I know how to properly use check boxes
- [x] I have included the version of Minecraft I'm running, baritone's version and forge mods (if used).
- [x] I have included logs, exceptions and / or steps to reproduce the issue.
- [x] I have not used any OwO's or UwU's in this issue.
