Thread safety error while compiling jmt crate

[mw2000]

Running into the following error when I try to compile my program which imports the jmt = 0.10.0 crate. How can I get around this? I implement a wrapper KeccakHasher around alloy_primitives::Keccak for which I implement the SimpleHasher trait.
