Add React Native support to the Typescript SDK

[JulienLavocat]

This PR helps to support React Native in the Typescript SDK. We have identified two issues:

1. Certain versions of React Native exhibit a bug where the constructor mistakenly treats a URL object as a string. This causes an error when the constructor attempts to call .endsWith() on the URL object, leading to runtime errors. This PR adds a .toString() call when passing a URL instance to the URL constructor.
2. React Native doesn't provide an implementation for TextEncoder and TextDecoder which are used to read/write strings in our binary reader and writer. This PR use introduce the usage of a library for these two types.

Note: this still requires the use of a Polyfill as React Native URL implementation is missing most methods in version older than 0.79 (>= 6 month old)
