Update README.md

Hi, I noticed three typos in this doc and propose changes accordingly:

1- Original: ...if successfull -- results in an authenticated and secure link...
Issue: Spelling error.
Correction: ...if successful -- results in an authenticated and secure link...

2- Original: ...one to continously read incoming data...
Issue: Spelling error.
Correction: ...one to continuously read incoming data...

3- Original: ...the connection is considered slow and unhealty and will be dropped...
Issue: Spelling error.
Correction: ...the connection is considered slow and unhealthy and will be dropped...
