Correction for max. length of advertised url to 17

Browse Source 
https://github.com/google/eddystone/tree/master/eddystone-url#frame-specification states 1-17
When one makes a general google for the max length, some have written 18 and some 17 :(
The difference could lie in the https://github.com/google/eddystone/tree/master/eddystone-url#url-scheme-prefix which adds an extra byte but it's use is to in someway allow for more bytes in the 1-17.
The implementation in the micro:bit Lancaster is unknown as to how the url-scheme-prefix is or is not used: there does not seem to be a scheme for "Just take the 1-17" for the url.

At the moment, "play it safe" and write 17 ?
