Add compilerOptions.paths support

[ihardlight]

Is your proposal related to a problem?

React scripts can not build app with custom relative paths as
compilerOptions: { "baseUrl": "./", "paths": { "@/*": ["src/*"], "~/*": ["../*"] } }
Error message: compilerOptions.paths must not be set (aliased imports are not supported)

Describe the solution you'd like

Using configuration from tsconfig file for aliases

Also related, when I've been running in react-scripts 3.4.3, it's been wiping paths from my tsconfig rather than crashing with a message. That's unacceptable.
