Slovak lang support

[misotrnka]

We've added support for SBD in Slovak language text.

Language specific improvements:

• list of common slovak abbreviations
• list of prepositive abbreviations
• list of number abbreviations
• handling of roman numerals
• handling of „ text “ quotes, that are common in Slovak language
• handling of ordinal numerals in dates, such as 17. Apríl 2020
• modified the replacement of periods in abbreviations, so it can consistently handle common Slovak abbreviations such as Company Name s. r. o.
• disabled processing of alphabetical lists, because of conflicts with some common abbreviations

The code has been tested for stability on a very large corpus of web text. The has been no rigorous testing for segmentation quality, but the subjective feeling in the team is very positive.

@misotrnka That's great! ✨

Can you add some tests for Slovak language as well?

Refer:
https://github.com/nipunsadvilkar/pySBD/blob/master/tests/lang/test_polish.py
https://github.com/nipunsadvilkar/pySBD/blob/master/tests/lang/test_russian.py

These tests will also act as a Golden Rules Set for Slovak language.
