ReadStat 1.1.1

• SAV reader: Allow spaces in timestamp strings

• README: Fix Windows / pacman instructions #189

• Fix </sortlist> errors opening files in Stata 15 (tidyverse/haven#461)

ReadStat 1.1.0

• New row offset API: readstat_set_row_offset(readstat_parser_t *parser, long row_offset)
  Call this function before parsing to skip a given number of rows in the file. In uncompressed formats, ReadStat will seek within the file for O(1) skipping performance. This allows client applications to offer chunked file reading. In compressed formats, data must be uncompressed first, and so skipping is O(n).

• Fix segfault when localtime fails on Windows.

• New error code: READSTAT_ERROR_BAD_TIMESTAMP_VALUE indicates a client-provided timestamp makes no sense.

• Renamed error code: READSTAT_ERROR_BAD_TIMESTAMP => READSTAT_ERROR_BAD_TIMESTAMP_STRING

• Fix implicit float-conversion warning (oss-fuzz/16372)
