A CLI tool to check type coverage for typescript code
This tool will check type of all identifiers, the code coverage = the count of identifiers whose type is not any / the total count of identifiers, the higher, the better.

run type-coverage
| name | type | description |
|---|---|---|
| -p, --project | string? | show where is the tsconfig.json |
| --detail | boolean? | show detail |
| --at-least | number? | fail if coverage rate < this value |
| --debug | boolean? | show debug info |
| --strict | boolean? | if the identifiers' type arguments exist and contain at least one any, like any[], ReadonlyArray<any>, Promise<any>, Foo<number, any>, is will considered as any too; also, future minor release may introduce stricter type check in this mode, which may lower the code coverage |

"atLeast": 99 // same as --at-least
