esbuild 0.8.56

Fix a discrepancy with esbuild's tsconfig.json implementation (#913)

If a tsconfig.json file contains a "baseUrl" value and "extends" another tsconfig.json file that contains a "paths" value, the base URL used for interpreting the paths should be the overridden value. Previously esbuild incorrectly used the inherited value, but with this release esbuild will now use the overridden value instead.
Work around the Jest testing framework breaking node's Buffer API (#914)

Running esbuild within a Jest test fails because Jest causes Buffer instances to not be considered Uint8Array instances, which then breaks the code esbuild uses to communicate with its child process. More info is here: https://github.com/facebook/jest/issues/4422. This release contains a workaround that copies each Buffer object into a Uint8Array object when this invariant is broken. That should prevent esbuild from crashing when it's run from within a Jest test.
Better handling of implicit main fields in package.json

If esbuild's automatic main vs. module detection is enabled for package.json files, esbuild will now use index.js as an implicit main field if the main field is missing but index.js is present. This means if a package.json file only contains a module field but not a main field and the package is imported using both an ESM import statement and a CommonJS require call, the index.js file will now be picked instead of the file in the module field.
