New Features

• Encode XML (vrt file format) with new function cwb_encode() that exposes functionality of cwb-encode CWB utility.
• Functions cl_cpos2lbound() and cl_cpos2rbound() will now accept an integer vector with length > 1 as argument cpos and return a vector with the same length. Useful to speed up iterated queries for left and right boundaries of regions (#19).
• A new function cl_struc_values() exposes the corresponding C function of the Corpus Library (CL). The previous implicit assumption that all structural attributes have values can thus be tested. Intended to work with annotations of sentences and paragraphs, i.e. common structural attributes that do usually not have values.
• A new function corpus_data_dir() will derive the data directory from the internal C representation of a corpus.
• New function s_attr_regions() will derive regions defined by a structural attribute from the *.rng file. Fastest option for large corpora.
• New functions s_attr_is_sibling() and s_attr_is_descendent() test the sibling/descendent relationship of structural attributes.

Minor Improvements

• Function check_corpus() now includes checks whether the registry provided (argument registry) is identical with the registry defined internally by CQP. The registry is reset if directories are not identical.
• Minor adjustments of configure script for aarch64, adding -fPIC to CFLAGS so that this flag will be used when Linux default configuration is used as fallback.
• The implementation of the s_attribute_decode() method was incomplete for method "Rcpp". This alternative to the "pure R" approach is now implemented (#2).
• The unused file 'setpaths.R' has been removed from the tools directory (#10).
• The argument method previously setting "wininet" in ./tools/winlibs.R is omitted to avoid the warning "the 'wininet' method is deprecated for http:// and https:// URLs" on Windows.
• The configure script will print the libdirs derived using pcre-config and link against libintl on macOS by default.
