HTTPS support on Pico!

I just tested, and the example code I posted works (although uploading it is sometimes a pain). I also generated new keys using the exact code below, and that works too:

// Steps taken from: 
// https://engineering.circle.com/https-authorized-certs-with-node-js/

wget https://raw.githubusercontent.com/anders94/https-authorized-clients/master/keys/ca.cnf  
openssl req -new -x509 -days 9999 -config ca.cnf -keyout ca-key.pem -out ca-crt.pem  

# Create a client key
openssl genrsa -out client1-key.pem 4096  
# get a config file
wget https://raw.githubusercontent.com/anders94/https-authorized-clients/master/keys/client1.cnf  
# Signing request
openssl req -new -config client1.cnf -key client1-key.pem -out client1-csr.pem  
# Sign
openssl x509 -req -extfile client1.cnf -days 999 -passin "pass:password" -in client1-csr.pem -CA ca-crt.pem -CAkey ca-key.pem -CAcreateserial -out client1-crt.pem  
# Verify
openssl verify -CAfile ca-crt.pem client1-crt.pem  

# Now get our keys into a format that can be used by Espruino.
# The following commands just strip off the first and last lines
# and remove all the carriage returns - this could be done by hand
# if needed.

sed '1d;$d' client1-key.pem | tr -d '\n'
# Copy, and paste into the quotes for `okey = fwrite( atob("") );`

sed '1d;$d' client1-crt.pem | tr -d '\n'
# Copy, and paste into the quotes for `ocert = fwrite( atob("") );`

sed '1d;$d' ca-crt.pem | tr -d '\n'
# Copy, and paste into the quotes for `oca = fwrite( atob("") );`
