  3. Moving Perl functions (Range index) to a common module. 

    Functions for forming the Range index in case mapping are transferred to a Perl
module.
From src/common/unicode/generate-unicode_case_table.pl to src/tools/Ranges.pm.
This is necessary for further use of this code to build Range indexes in Unicode
normalization.

  4. Improve the performance of Unicode Normalization Forms. 

    This changes significantly speeds up the normalize() function.
Similar to the changes in case mapping (fold, lower, upper, or title case),
here we get rid of perfect hashing and replace it with a range index with
a nested branch function to check specific ranges of code points.
This allows us to achieve a performance increase of up to 40%.
