feat: Multiline braille display support for multiline plot

[soundaryakp1999]

Feature Request

Motivation

Multiline braille displays can help compare the lines in a multiline plot by representing each line separately. I do not recommend to represent multiple lines in the same braille line for intersection purposes, as the vertical dimension is limited, and it is impossible to identify different lines.

Proposed Solution

1. Represent the different lines separately that is, line 1 should be displayed on line 1 of the braille display.
2. If number of plot lines exceeds number of lines in braille display, let the user scroll in the y dimension, preserving the x axis points.
3. If number of cells in a single line is insufficient to represent the entire length of a line, let the user scroll left to right. All lines should scroll simultaneously so that the user can identify relative similarities and differences between the lines in same x axis value.
