Release/v0.5.0 (#15)

## Features:
- Create migration up/down to start the project from scratch.
- Ensure that all files are created and not replaced when using
generateFile. If the file doesn't exist, it creates a new folder + file;
if it exists, it opens the file and returns the fd file descriptor.
- Validate if installed drivers and create a query connection to run
migrations. New rules were added to ensure that all necessary drivers
like MySQL and SQLite3 are installed.

## Chore:
- Removed an unused file.
- Removed an unused method.
- Removed an unused type
- Created templates for migrations.
- Created version to v0.5.0.
