Free timer interrupt on Pico W when end function is called

[Adventurer21]

Firstly, for information purposes, this library works perfectly on the RP2040 based PicoW (V1).

Now, for my request. The RP2040 has a RTC, but without a battery-backup. So I'd like the ability to query the NTP server once, during setup to use the returned value to set the RTC. No updates.

I notice that the timeClient keeps track of the current time even-though I called the end function, so the timer interrupt is still captured. Can we free that interrupt when the end function is called?
