Stack overflow in Document::has_leading_newline on large document

[greenhat]

The stack overflow occurs in the recursion at

miden-formatting/formatting/src/prettier/document.rs

Line 52 in edcd537

Self::Concat(a, _) => a.has_leading_newline(),

during pretty printing.

To reproduce: print a midenc_codegen_masm::Program emitted with stdlib.

Workaround: increase the stack size via RUST_MIN_STACK=104857600 env var.
