Subject: [PATCH] fix build breakage with newer cdproto versions

This isn't strictly necessary, as one can always build with the earlier
cdproto version specified in go.mod. However, many people still install
chromedp in GOPATH via 'go get -u', so this workaround makes life easier
for a lot of developers.

Fixes #285.
