[2]Binary 🔋batt level

1. Automate Community
2. Personalization

Shows notification where battery level is shown as octal, on a scale from 0 to 63 inclusive [0o00, 0o77].

63 is the highest Mersenne less than 100, which means the downscaling preserves the most precision.

Hexadecimal doesn't have "6bit symmetry" (max is 0x3F). The aesthetic choices are base 2, 4, and 8, latter being most efficient.

To save energy, I precomputed the text using this expression `(n >> 3) ++ (n & 7)`, where `n := round(l * 0.63)`
