Adding daml language support to linguist. DAML is an open-source smart contract language.

Checklist:

• I am adding a new language.

    • Search results for each extension:

The in-the-wild usage requirement is blocking here. Is there any reason to believe usage will increase significantly in the next few months? Was the language recently created?

[akalburgi]

Daml is a relatively new language and was recently open sourced (on April 4th) thus the open source usage is just taking off. We have seen very enthusiastic response form the community, we have close to 500 active developers (https://damldriven.slack.com/messages/C94RD7677/details/) and growing StackOverflow community.

Any reason for choosing "Daml" for the language name (instead of DAML) when everything on the official site you've referenced calls the language "DAML"?

[akalburgi]

Good point, let me get back to you.

@akalburgi I'll add the extension to #4219 and will post a message here if/once it becomes popular enough.

[akalburgi]

Thank you for the update.

[pchaigno]

Closing in favor of #4219. We'll monitor the popularity of the extension there.

If you have improved search queries compared to those I used in #4219, please post them here and I'll update #4219.
