Add CPU Architecture check for aarch64 (on Linux)

• use regular arm binary as Terraform currently does not have a separate binary for arm64

Adjust movement of binary from download folder to destination

Add arm processor detection

Adjust latest_version algorithm to exclude alpha releases

fix latest version checking

• latest version fixes
  • no longer includes beta and rc versions
  • no longer requires sort --versions-sort argument in jq-based algorithm [issue #4]
• gather latest version only when necessary and after help [issue #4]
• added set -e error trap [issue #4]

Add checksum validation of downloaded file before installation

Correct fallback value for cpu architecture detection.

Adjust for use in CI/DevOps pipelines

Added -c option to leave binary in current directory (for CI/DevOps use)

Compatibility Release - works with either curl or wget and uses jq if installed

• checks for either curl or wget and uses whichever is present
  • defaults to curl if both installed
• if jq is installed - parses the latest version from hashicorp download page (instead of GitHub)
  • Avoids github api limit of 60 unauthenticated requests per hour
  • Useful if github release differs from version on hashicorp downloads

Adds check for wget submitted in PR #3

• Corrects error on macOS with default awk when detecting latest version
• Switched to wget instead of curl throughout, removing curl as a dependency
• Fixed spelling & adjusted help message

CPU Architecture Detection Algorithm Enhanced

• new common algorithm that works across deb and rpm distros
• uses lscpu results to determine CPU Arch if possible
• as a fallback it searches the flags in /proc/cpuinfo to determine Arch
• if arch is an arm variant, changes to just "arm" for proper function in Terraform download URL

Added parameter and variable to allow script to run without prompting for install destination

• -a parameter specifies to always use sudo to install to /usr/local/bin
• This can be set as default by uncommenting line 14 to set sudoInstall=true
• user may need to enter sudo password unless password-less sudo is enabled
