Description: Fix source-map type incompatibilities with version 0.6.x
 Debian ships source-map 0.6.1 but ts-loader expects 0.7.x.
 The API differences:
 - destroy() doesn't exist in 0.6.x (use optional chaining)
 - RawSourceMap.version is string in 0.6.x, number in 0.7.x
 - Types don't declare toJSON() but it exists at runtime
