Add support for MIUI Browser

[Suaro]

Hello,

Currently when you access from a MIUI browser, your library is returning Chrome.

The MIUI Browser user-agent can be correctly differentiated:

Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/534.24 (KHTML, like Gecko) Chrome/71.0.3578.141 Safari/534.24 XiaoMi/MiuiBrowser/12.4.4-g

I understand that the output should be something similar to:

{name: 'miui', version: '12 .4.4 ', os:' Android '}
