Fix 3D format detection when the tag is the last token of the path

Format3DParser drops the last character of the final path token: when
IndexOfAny finds no more delimiters, the slice is taken with
'index = path.Length - 1', so e.g. "hsbs" is compared as "hsb" and
never matches any rule.

File paths are unaffected because the extension is always the final
token, but directory based media have no extension. For DVD/BluRay
folder rips (BaseVideoResolver parses the folder path via
Set3DFormat), a trailing 3D tag such as
"Gravity (2013) 3d hsbs/BDMV" is silently ignored and Video3DFormat
is never set.

This is a regression from 42a2cc174 which replaced the string.Split
based FlagParser with span slicing; the Split implementation kept the
final token intact.
