doh.replace is not a function

Hi, I tried bulldohzer on an up-to-date arch linux, but I get the following error:
```
LC_ALL=C nvm exec 12 -- npx bulldohzer --doh
Running node v12.20.1 (npm v6.14.10)

Note: I ran it with nvm to ensure this is not related to a specific node version, but the same error occurs when ran outside nvm
