The purpose of this class is to provide enough
information about its data to create a PostScript version.
Thus it must provide the following to the caller:

+ min width of each column for its content and font
+ min height of each row for its content and font

While each cell can have its own font, it is generally
better to have row 0 be the header and the other rows
contain the data.  The default is to use Times-Roman 
for the data and Times-Bold for the header row.

RSV - encoder and decoder of Rows of String Values


=begin code :lang<raku>

use RSV;

my blob8 $rsv = to-rsv(@array);
my @array2 = from-rsv($rsv);

=end code


RSV is a binary format for storing simple string values. As the name suggest, it support only Rows of String Values. It is not a generic serialization framework, but more of a replacement of CSV or TSV.


The C<RSV> module provide two functions: C<to-rsv> and C<from-rsv>.
                                                                                         C<to-rsv> function is a RSV encoder that produces a blob8 value from the given input. The input must be an array, in which each element must be an array of string or null value. Or in a more concise type-annotion: C<Array[Array[String|Nil]]>
