wadptr 3.8

• The -u ("uncompress") option was renamed to -d ("decompress", the usual terminology used by almost every other compression tool).
• A bug was fixed that made the Windows version for the previous release not work properly; a dependency was unintentionally added on the pthreads API, the DLL for which was not included in the release. That dependency has now been removed. Thanks to @Anonysussy and @happygreenfairy for the bug report.
• A special sector tag range (9700-9799) is now recognized for special effects. There are some cases where level authors may deliberately want sidedefs to be merged even when they are attached to special lines, and this allows that. Thanks to @kitchen-ace for the suggestion.
• The manpage has been expanded somewhat.
