Need for additional esbuild options: exlude and keepNames

[zjpalasz]

Currently, when trying to bundle node-postgres, the following error occurs:

node_modules/pg/lib/native/client.js:4:21: error: Could not resolve "pg-native" (mark it as external to exclude it from the bundle, or surround it with try/catch to handle the failure at run-time)

The only solution I've come across is to exclude: ['pg-native'] via the esbuild options.

Additionally, when trying to bundle azure/storage-blob, the following error occurs:

Error: TypeError: Expected signal to be an instanceof AbortSignal

It seems to be related to the sdk's dependency on node-fetch as noted here. The suggestion of using keepNames: true, seems to resolve the issue.

Closed by #51. Please open another issue for keepNames if you find that it is still needed, per #51 (comment)
