Rename packages (nyc -> coverage, prettier -> format, tsc -> typescript)

[ryanio]

As per https://github.com/ethereumjs/ethereumjs-config/pull/26#issuecomment-588427106 and to close https://github.com/ethereumjs/ethereumjs-config/issues/18, this PR renames:

• ethereumjs-config-nyc -> ethereumjs-config-coverage
• ethereumjs-config-prettier -> ethereumjs-config-format
• ethereumjs-config-tsc -> ethereumjs-config-ts-compile ethereumjs-config-build -> ethereumjs-config-ts-build

ethereumjs-config-tslint is renamed to ethereumjs-config-lint in #26.

This PR also removes coveralls since we can now push reports via github actions (closes #22).

I looked at past PRs, and it seems we can safely ignore LGTM analysis for JS. Merging in…
