WebGL build for companion app

We'd like to have a companion mobile / webgl build for our application. The meta sdk is making this impossible to do with the same unity project.

In unity 6 with v69 of meta sdk

When switching to webgl we get this error: 

Library/PackageCache/com.meta.xr.sdk.voice/Lib/Wit.ai/Scripts/Runtime/WitRequest.cs(376,17): error CS0103: The name '_log' does not exist in the current context

Looking at the code, it appears that this _log does indeed not exists. Because this is now in packages, we cannot simply comment out this line.

I am starting a 2nd project but this is just a minor programming mistake that should be addressed to allow others to not have to make a 2nd project for this type of functionality.
