Add "Pretty print" option for all output formats

[meinsiedler]

Add an extended feature option "Pretty print" for LaTeX, Jira and Markdown output which aligns the columns so, that all column separators will be aligned one below the other.

For Jira output for example, instead of

| 1 | 22 | 333 |
| 4444 | 55 | 6666 |

with "Pretty print" enabled, the output is

| 1    | 22 | 333  |
| 4444 | 55 | 6666 |

Note that there are basically three options how the content should be aligned:

1. Let the user manually set the alignment of the content (left, right, center) for all cells.
2. Set alignment based on content type (e.g. right align numbers, left align text).
3. Set alignment based on the cell alignment in Excel.

❗️ Also note that column separators can have different length. For example, the Jira header column separator is || while the normal column separator is |.
