Add option to skip left and right borders

[rovo89]

Similar to top_and_tail, this adds an option to remove the left and right borders. It works with all three styles.

Example:

use Text::Table::Tiny 1.02 qw/ generate_table /;

my $rows = [
  [qw/ Pokemon     Type     Count /],
  [qw/ Abra        Psychic      5 /],
  [qw/ Ekans       Poison     123 /],
  [qw/ Feraligatr  Water     5678 /],
];

print generate_table(rows => $rows, header_row => 1, left_and_right => 1), "\n";

Will generate the following:

-----------+---------+------
Pokemon    | Type    | Count
-----------+---------+------
Abra       | Psychic | 5
Ekans      | Poison  | 123
Feraligatr | Water   | 5678
-----------+---------+------

Or combined with top_and_tail (for which I introduced a shortcut edges):

print generate_table(rows => $rows, header_row => 1, top_and_tail => 1, left_and_right => 1), "\n";
print generate_table(rows => $rows, header_row => 1, edges => 1), "\n";

Pokemon    | Type    | Count
-----------+---------+------
Abra       | Psychic | 5
Ekans      | Poison  | 123
Feraligatr | Water   | 5678

Note that this is based on #15 for Perl 5.8 compatibility, the actual changes can be seen in d57779d?w=1. If the other PR is not accepted, it's trivial to rebase it to master instead. Also I didn't add documentation and tests yet, happy to do that if there's interest in this enhancement.

I'm not sure about the name left_and_right.

The phrase "top and tail" is an established idiom for cutting the top and bottom off something, but "left and righting something" isn't.

I can't think of an obvious alternative so far. Thoughts are

no_sides => 1

which also made me wonder about

no_frame => 1

or

no_border => 1

meaning no orders on any of the sides.

I don't like the no_ in an option which is then set to a truthy value, but may be unavoidable.

Ah, as a non-native speaker I didn't know this idiom and was confused why you would enable the top and tail option to actually get rid of them. 😊

I guess some "-less" might sound a little less strange, as in "frameless" or "borderless". But yeah, not easy to find something clwae and precise.

Staying with the original idiom, maybe "peel" could mean slicing off the other parts of the fruit. 😉

Ha. Ok, I apologise for "top and tail"! :-)

I wonder whether something like:

frame => "none"
frame => "TB"
frame => "TBLR"
frame => "all"

but such a general purpose option seems overkill – who is going to use "TR", for example?

And I was thinking, would "NSEW" be better than "TBLR"?

I'll mull some more.
