Description

Re-write the transport read and slip parsing to match esptool.py. This method should remove the timeout issue seen in most reported issue.

Update stubs to match current esptool.py stubs. Change baud issue in #159 was probably due to stub entry not matching.

Testing

You can test on my fork in https://brianignacio5.github.io/esptool-js/

Or test by npm run dev the examples/typescript after npm run build in root directory. This will generate a localhost version of https://espressif.github.io/esptool-js/ to test.

You can compare the trace output of esptool.py with esptool-js (there is a copy trace button that will copy the trace in clipboard or just review the Developer Tools console output).
