Long version:
Putting an SPS|XPS into the PSU input would read as if the file was very long, so added a 127-file limit (I think this is reasonable) to prevent prolonged stalling.
Added SPS|XPS support to the library, which is the third most common contained format besides PSU and PSV.
Updated demos.
Technical changes:
removed unused u16le definition from readEntryBlock(), since permissions are better read as a u32 instead
added PSV and SPS|XPS reader functions to c6 exports, since I forgot in 0.3.4
moved some stuff around in HTML demo, especially the old raw icon.sys and icon input boxes, since I'm finding parsing a collection of files more useful then the actual standalone files themselves.
HTML-demo: added an "show advanced options" checkbox that unhides features deemed too niche for conventional use
