process is not defined in browser

Issue when import avro from "avsc/etc/browser/avsc-types";.

#486

I think there are many ways to resolve the issue, but the key is not to use util when in browser.

Which bundler are you using?

[bill-min]

Its customized stuff and I am using esbuild for one use case. I don't really like the fix personally, but seems like most straightforward change, if we are going to refactoring this lib to use esm and latest stuff anyway. One other way is to use util-browser instead of util when require from /etc/browser, but you are going to add one more dependency.

Resolved in #486.
