[FR] Add analyzer for CIS MCAP

[joeslazaro-cdw]

Feature description
The Center for Internet Security (CIS) provides an API for their Malicious Code Analysis Platform (MCAP), a no-cost web-based sandbox. CIS is home to MS-ISAC (Multi State Information Sharing and Analysis Center) and EI-ISAC (Elections Infrastructure Information Sharing and Analysis Center). MCAP allows MS-ISAC and EI-ISAC members to submit suspicious files such as executables, DLLs, documents, quarantine files, and archives for analysis in a controlled and non-public fashion. The platform also enables users to perform threat analysis based on domain, IP address, URL, hashes, and various Indicators of Compromise (IOCs).

Describe the solution you'd like
I have a working analyzer for which I am preparing to submit a pull request.
