[bug#68448] Add guile-rsv package definition.

[Yuval Langer <yuval.langer@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 454 bytes --]

Hi,

this library implements the Rows of String Vectors file format as
specified by Stenway[1], an alternative to Comma Separated Values and
similar file formats.

It also provides two commands, rsv2scm and scm2rsv, for reading and
writing RSV files to and from a list of lists of strings.

The main repository is on Codeberg[2].

Many thanks,
Yuval Langer.
