add vendor deebot_slim

[mib1185]

Hello,

I have an ecovacs deebot slim 2 (I call it Bob), which provides component_side_brush and component_filter in full hours, therefore no extra calculation on values is needed. In addition, the deebot slim series has no main brush equiped, therefore the translation of key-name is not needed. I would love to remove the field for the main brush from view, but my JavaScript skills are very limited :)

entity data of my vacuum.bob

fan_speed_list:
  - normal
  - high
battery_level: 100
battery_icon: 'mdi:battery-charging-100'
fan_speed: normal
status: charging
error: null
component_side_brush: 35
component_filter: 18
friendly_name: Bob
supported_features: 2043

as you could see, usage counter for side brush and filter is now correct, but main brush has no value:

Hello, and thank you for the contribution! I am currently working on a new version of this plugin, so I will add an integration for Deebot Slim while doing so. I will fix the main brush issue too :)

Also, if you don't mind uploading that background image you are using here, I could add it to the image folder in this repository so that others can use it too 😄

Should be supported in version 4.0.0

Hi,
because the picture I am using is not created by me (found on google picture search), I´m not sure, if it is allowed to upload this picture to this repostirory?!
P.S.: thanks for accepting my pull request and for fixing the main brush 'issue' :)
