Fix: Minor Readme Duplicate & Update Deps

[f3rno]

Hi,

I spotted a minor but slightly 'large' error in the readme.md, specifically 2 Signale constructor options hash keys were duplicated and documented twice. I've removed the extra lines, and updated all dependencies to latest versions. Currently untested, but npm run test fails due to typescript-eslint/typescript-eslint#2010 (fix merged but awaiting release). It should work once @typescript-eslint is updated.

Changes

• minor fix in readme.md
• bumped chalk from ^2.3.2 to ^4.0.0
• bumped figures from ^2.0.0 to ^3.2.0
• bumped pkg-conf from ^2.1.0 to ^3.1.0
• bumped package version to 1.4.1

TODO

• verify yarn test after @typescript-eslint is updated in npm registry
