Adding the possibility of inserting an arbitrary EOF

[radziksh]

@Quramy @olegstepura first of all, thank you for your great work!

In our project we use git with different operating systems, and for the convenience of development we decided to store our files with LF ending. We use typed-css-modules-loader which passes the parameters to the typed-css-modules via options:

{
  loader: 'typed-css-modules-loader',
    options: {
        // params for typed-css-modules
    },
},

the problem is that when the programmer that uses Mac os generates a change, then the d.ts file is saved in the LF format, and if the programmer that uses Windows does this, the d.ts file is saved in the CRLF format. Because of this we see many changed files in which there are actually no changes:

all changes are just EOL:

we needed to directly specify the type of EOL that we need, but unfortunately this option was not available and we had to create a fork. Perhaps this option will be useful to other users, so I created a pr.

usage with typed-css-modules-loader:

{
  loader: 'typed-css-modules-loader',
    options: {
      EOL: '\r\n', // or '\n'
   },
},

If there are no options, then by default, there will be an old behavior with an os.EOL

@radziksh Thanks for your PR . It looks nice ;)
Whould you write doc about this EOL option to README https://github.com/Quramy/typed-css-modules/blob/master/README.md#new-dtscreatoroption ?
