Diskuv OCaml 1.0.1 Release

This is mostly a bug fix. It is available at https://github.com/diskuv/dkml-installer-ocaml/releases/download/v1.0.1/setup-diskuv-ocaml-windows_x86_64-1.0.1.exe and the full release notes are at Release v1.0.1 · diskuv/dkml-installer-ocaml · GitHub

Summary of changes:

• The installer now checks whether files are in use when overwriting a previous installation just like the uninstaller already did.
• Fix Dune shim so dune build works consistently on Windows. Missing `advapi32.lib` and `uuid.lib` when compiling with dune · Issue #6 · diskuv/dkml-installer-ocaml · GitHub
• Fix detection of Jane Street package versions so ppx_jane dependencies like fieldslib, and other JS packages, are pinned to versions like v0.14.0 (etc.). Also pin transitive dependencies of ppx_jane. ppx_jane cannot be installed · Issue #8 · diskuv/dkml-installer-ocaml · GitHub
• MSYS2 variables are available as Opam global variables. The list is here. For example, opam var --global msystem is CLANG64 and opam var --global mingw-package-prefix is mingw-w64-clang-x86_64. They will become useful when Opam depext functionality is added for MSYS2.
• Fix version in Add/Remove Programs that was dev instead of 1.0.1 (etc.)
