Added bullet “Water resistant or waterproof if placed inside DS9107 iButton capsule

UL bullet and safety statement; added text to Application section: Note that the initial
sealing level of DS1922L/DS1922T achieves IP56. Aging and use conditions can
degrade the integrity of the seal over time, so for applications with significant
exposure to liquids, sprays, or other similar environments, it is recommended to place
the Thermochron in the DS9107 iButton capsule. The DS9107 provides a watertight
enclosure that has been rated to IP68 (See www.maximic.com/AN4126)
