http response handling changes of epsagon 1.56.1 still produce runtime errors

[tripodsan]

even with the recent fixes of #244, we're still seeing errors with epsagon enabled, that are otherwise not a problem:

RangeError: Resource length mismatch (possibly incomplete body)
    at throwLengthMismatch (./node_modules/fetch-h2/dist/lib/body.js:17:11)
    at StreamResponse.validateIntegrity (./node_modules/fetch-h2/dist/lib/body.js:167:13)
    at awaitBuffer.then.already_1.tap.buffer 

could be caused by epsagon, consuming the chunks of the response.

running the example shows:
