Splat crashing LSP. Ref tree-sitter-c3#22

While the following is valid C3 it make the LSP and highlighting crash. `Rectangle pos = {...frameRec, ...spriteSize};` Where Rectangle is something like `struct Rectangle { x, y, h, w };` (pseudo code). This is perfectly fine c3 syntax and should not crash the LSP. I am using the lsp with Helix on Arch. c3-lsp is installed from source.
