Dot-Env Conversion v3.0.0

Changes:

• auto:boolean and boolean conversion methods now accept additional original values:
  • True values: ok, Ok, OK.
  • False: not, Not, NOT, none, None, NONE.
• Binary (0b...) , octal (0o...) and hexadecimal (0x...) number syntax are now accepted in auto:number, auto:bigint, boolean, number, bigint conversion methods.
• Empty array ([], [ ], ...) or empty object ({}, { }, ...) are now accepted in boolean (converted to false), number (converted to 0) and bigint (converted to 0n) conversion methods.
• Conversion now ignores non-string environment variables.
• Add Documentation to README.md.
• Update ignore files.
• Do some small refactor.
• Enhancements:
  • switch(true) turns into if ... return ... blocks.
  • Values that could be matched with an exact converted value now are cached in specific lookup tables -> reduce the cost of executing if statements.
  • flattenValue is now more detailed.
  • restoreValue now ignores non-string values.
