I would like to suggest adding more Saw variants to ProjectRed Exploration (Minecraft 1.21.1), starting with a Copper Saw.

Currently, the Saw is required to cut Silicon Boules into usable Silicon. At the moment, only the Diamond Saw works for this process. This makes early-game progression a bit restrictive.

Proposed improvement:

• Add a Copper Saw (and potentially Aluminum, Bronze, etc. variants).
• Allow all Saw variants to be used for cutting Silicon Boules.

Additional context:
In my custom modpack I temporarily solved this by editing the recipe JSON to use a tag instead of a specific item (tag: "cb_microblock:tools/saw").
A Copper Saw would provide a more natural early-game tool progression, before reaching Diamond.
