Improve installation: Use /usr/local/bin & simplify manual install

[shv-ng]

Description:

This PR improves the installation process by:

1. Using /usr/local/bin instead of /usr/bin

   • /usr/local/bin is the recommended location for user-installed binaries.
   • Avoids potential conflicts with system-managed packages.

2. Simplifying manual installation in the README

   • Instead of manually cloning, navigating, and running chmod +x, users can now install with a single command:

     curl -sL https://raw.githubusercontent.com/orhnk/RASCII/refs/heads/master/install.sh | sh

   • This makes installation faster and easier for users.

These changes follow best practices and improve the user experience.

Summary by Sourcery

Update the installation script to install the binary to /usr/local/bin instead of /usr/bin. Simplify the manual installation instructions in the README to a single command.

Enhancements:

• Use /usr/local/bin for binary installation, which is the standard location for user-installed executables and prevents conflicts with system packages.
• Simplify manual installation with a single curl command that clones the repository, builds the binary, and installs it.

Hey @ShivangSrivastava - I've reviewed your changes - here's some feedback:

Overall Comments:

• Using curl | sh for installation is a security risk - users should be encouraged to download and inspect the installation script before running it. Consider providing the manual installation steps alongside a downloadable script.
• The installation script assumes the RASCII directory doesn't exist and could fail if it does. Please add appropriate error checking and directory handling.

Here's what I looked at during the review

• 🟡 General issues: 1 issue found
• 🟢 Security: all looks good
• 🟢 Testing: all looks good
• 🟢 Complexity: all looks good
