Patch to Max time slot render

[cardiffinc]

• Max time slot was missing in the render.
• Added the missing <= to render the max time slot

Hi @cardiffinc, maxTime is intentionally an exclusive boundary as it represents the time at the bottom edge of the selector, e.g. in the live example, the max time is 5pm, reflecting that the last time cell ends at 5pm.
