[stunnel-users] when reload configure，there is a err (win32)

hi,I am using the latest version(stunnel5.58) on windows10; compiled openssl 1.1.1j with option zlib enabled;

the stunnel.conf file: add option "securityLevel = 0" to enable compression add option "compression = zlib" to enable compression

when stunnel start,it work well.but when i reload configuration in the menu configuration，it give me this:

SSL_COMP_add_compression_method: ssl\ssl_ciph.c:1997: error:140A5135:SSL routines:SSL_COMP_add_compression_method:duplicate compression id Global options: Failed to initialize TLS

Then i search the source code,i found when reload config,the SSL_COMP_add_compression_method(0xe0,mesh) function will add compression id again(duplicate)

i hope this can be fixed,thanks.
