Add support for Infura Project Secrets

[naddison36]

Infura has added support for an optional project secret to their API.

From https://infura.io/docs/gettingStarted/authentication
"As additional protection for your request traffic, you should use HTTP Basic Authentication to access our API when you are able to ensure the confidentiality of the Project Secret:"

curl --user :YOUR-PROJECT-SECRET \
  https://<network>.infura.io/v3/YOUR-PROJECT-ID

It'd be good if the InfuraProvider construction could take an optional project secret argument that is used to do the HTTP Basic Authentication.

Thanks

Good catch, I had not noticed that you could use that for authentication.

I'll add it soon. :)

I've added a PR to add this functionality. Please take a look and let me know what you think.

This was added a while ago to v5. I'm going to close this issue now, but if you have any problems, please re-open, or create a new issues.

Thanks! :)
