format - add lines for rows and columns when using csv input

[danie-dejager]

Is your feature request related to a problem? Please describe.
I would like to create a table from CSV input. I use rich-cli to format my CSV output but ideally gum should do that too and I will need one less tool.
Original:

using rich-cli:

What I'm getting is a table from which I can select a specific line which will get printed to the command line.

Describe the solution you'd like
I want gum to format csv or similar input like rich-cli is doing.

Why does gum work below but I cannot format CSV?

echo "## Test:
|Name            |Bool             | Source     |
|----------------|-----------------|------------|
|a1              |Yes              |local	|
|b1              |Yes              |local       |
|c1              |Yes              |local       |
|d1              |Yes              |remote      |
"  | gum format

Name	Bool	Source
a1	Yes	local
b1	Yes	local
c1	Yes	local
d1	Yes	remote

Describe alternatives you've considered
rich-cli can format my CSV input into columns with minimal effort.

Hi @daniejstriata. You can use gum table -p. It was introduced on #436 so you will need to use the git version of gum.

I think something like this would work for you.

echo "
a1,a2,a3,a4,a5
b1,b2,b3,b4,b5
c1,c2,c3,c4,c5
d1,d2,d3,d4,d5
"  | gum table -p

I built the binary from git in the main branch and it is working!
I see it assumes that the first row is a header.

otherwise I can specify headers:

If I give a header with no data then the column is not drawn.
