Support level being passed in as an environment variable

[jmac105]

Hi,

I'd find it really useful if the level option could be passed in as an environment variable, as it can be to the native npm audit command via NPM_CONFIG_AUDIT_LEVEL environment variable. This would allow for setting a global audit level across all of our CI pipeline builds, some of which use 'npm audit' and some of which use 'better-npm-audit audit'.

Would you consider a PR which would set a default value for level as a fourth parameter here

better-npm-audit/index.js

Line 173 in 7ad4a72

.option('-l, --level <auditLevel>', 'The minimum audit level to validate.')

, taking the value from process.env.NPM_CONFIG_AUDIT_LEVEL?

Cheers
