Support for Angular 6 + RXJS 6

Having issues using Angular 6. The first being RXJS imports being different, which is able to be avoided by importing the rxjs-compat package.

The second issue when using ng6 is the following:

ERROR in node_modules/ngx-material-file-input/src/file-input/file-input.component.d.ts(7,22): error TS2720: Class 'FileInputComponent' incorrectly implements class 'MatFormFieldControl<FileInput>'. Did you mean to extend 'MatFormFieldControl<FileInput>' and inherit its members as a subclass?
  Property 'shouldLabelFloat' is missing in type 'FileInputComponent'.

Seems a new property was added in MatFormFieldControl that needs to be implemented within FileInputComponent.

Migration done! For version with angular 6 -> see 0.2.0

can get it working by manually for now by making the following change before compile.

edit: node_modules/ngx-material-file-input/src/file-input/file-input.component.d.ts

add shouldLabelFloat: boolean;

so it looks something like like.

export declare class FileInputComponent implements MatFormFieldControl<FileInput>, ControlValueAccessor, OnInit, OnDestroy {
    shouldLabelFloat: boolean;
    ngControl: NgControl;
