Adding tiny-trie package to React/ReactNative project causes multiple "Failed to parse source map" warnings. #15

Problem

Adding tiny-trie to a React or React Native project causes a bunch of warnings to be thrown when starting the project:

WARNING in ./node_modules/tiny-trie/lib/BinaryString.js
Module Warning (from ./node_modules/source-map-loader/dist/cjs.js):
Failed to parse source map from './node_modules/tiny-trie/src/BinaryString.ts' file: Error: ENOENT: no such file or directory, open './node_modules/tiny-trie/src/BinaryString.ts'

WARNING in ./node_modules/tiny-trie/lib/Trie.js
Module Warning (from ./node_modules/source-map-loader/dist/cjs.js):
Failed to parse source map from './node_modules/tiny-trie/src/Trie.ts' file: Error: ENOENT: no such file or directory, open './node_modules/tiny-trie/src/Trie.ts'

# and other, similar warnings...

Repro steps

I quickly spun up this repo that's set up to repro this issue. Just clone the repo and do: npm i && npm start. Alternatively, you can set up a new React project that triggers the issue by doing:

# 1. Create the project.
npx create-react-app repro

# 2. Navigate to the project's folder.
cd repro

# 3. Install the package.
npm install tiny-trie

# 4. Import a class from the `tiny-trie` package in any source file.
# ...

# 5. Start the project.
npm start

Here's a similar issue in some other project and it's corresponding fix.
