feat: support blob responses

[jd1378]

Resolves #385 and unjs/nitro#1237

Would you please add a unit test? 🙏🏼

[jd1378]

Well during writing tests I realized the real issue was that Blob type was not being handled properly, which was why the fix was working, So I handled it in app part
but still I saw when empty string is returned along with 304, it has problem handling it and responds with 500, so I still added the test and fix for that part as well

I have pushed a commit to fix the lint issues but I don't the commit in the PR, what am I doing wrong ? is it me or github being funny ?

[jd1378]

yeah it was GitHub, re-set the base branch on edit dialog and it showed up
