 Introduce ryu to print doubles

 This massively (x10) speeds up lwprint_double and will be followed up
 by improvements to improve other output functions that rely on it.

 There has been some complications in adapting the function itself since
 the output used by Postgis is by no means standard, choosing the number
 of decimal digits based on the integer digits, user input and size
 of the input buffer (although it should always be big enough)

 Closes #4543
