Returns a path to the binary in the form of {home}/.unc/unc-node-sandbox-{hash}/unc-node-sandbox
Installs sandbox node with the default version. This is a version that is usually stable
and has landed into mainnet to reflect the latest stable features and fixes.
Install the sandbox node given the version, which is either a commit hash or tagged version
number from the nearcore project. Note that commits pushed to master within the latest 12h
will likely not have the binaries made available quite yet.
