Home Variable Expansion on Windows When Loading A Session Results in Malformed Path

[Sealatron]

Bug description
On Windows, I have my HOME environment variable set to "HOME=D:\". When reloading a CMake project session via Lazyvim, cmake-tools attempted to mkdir a malformed path to store/access session data.

I believe the culprit to be cmake-tools.nvim/lua/cmake-tools/session.lua:8:

    win = vim.fn.expand("~") .. "/AppData/Local/cmake_tools_nvim/",

Steps to reproduce

Minimal configuration

Set Environment variable HOME=D:\ A session exists in a CMake project directory.

1. Attempt to load a CMake session, such that `init_cache` is called.

Expected behavior

1. I would expect cmake_tools to use the nvim-data directory, which could be accesed via vim.fn.stdpath("data") .. "/cmake_tools_nvim" instead of attempting to create another folder in my User area.
2. Failing that, instead of doing vim.fn.expand("~") on Windows, the Users Local AppData directory can be accessed via the environment variable %LOCALAPPDATA%.
3. Failing either of those, perhaps the cmake_tools_nvim directory could be specified by users in the config.

Sorry, not sure where this buffer is? I can update with that info if necessary.

Thanks for reporting - I like the idea of using stdpath for that.
Mind giving this branch a try?
