So let's remove speed from ru-cl also

added tests to:
- language-numbers-cardinal.test
- tests/language-phonemes.test
- tests/language-pronunciation.test

This commit implements support for [Totontepec Mixe](https://en.wikipedia.org/wiki/Totontepec_Mixe). The Espeak rules are based on the phonological inventory, orthographic mappings, and phonetic processes described in the "Esbozo fonológico" (phonological outline/sketch) chapter of Verónica Guzmán Guzmán's 2012 master's thesis in Indo American Linguistics awarded by the [Centro de Investigaciones y Estudios Superiores en Antropología Social](https://ciesas.edu.mx/) and *Vocabulario Mixe de Totontepec* (Totontepec Mixe vocabulary), compiled by Alvin Schoenhals and Louise C. Schoenhals and published by the Summer Institute of Linguistics in 1965.

This commit was developed as part of a project for [Computational Linguistics](https://jnw.domains.swarthmore.edu/ling073/syllabus.php) at [Swarthmore College](https://swarthmore.edu). We feel that this language is suitable for merge with "testing" status, but further verification/improvements by native speakers would be very helpful.

When pollint() returns 100.0, multiplying by 2.55 doesn't actually seem to
be getting 255 on i386. Multiplying by 255 and dividing by 100, however,
does (probably because float computation with small integer values are
guaranteed to have integer results).

Fixes #1151

This reverts commit 433d219eca.

This reverts commit 02783150cd.

182aba4cc started calling Norwegian nb instead of no. The result is that
code in tr_languages.c was never run.

Added tests are copied from existing tests from the same language family
or English. The tested phonemes should be adapted for better test
coverage.
