Incorrect @Input size typing when strictTemplates is enabled

Describe the bug AOT compilation build under Angular 9 with angularCompilerOptions.strictTemplates: true in tsconfig.app.json generates a error TS2322: Type 'string' is not assignable to type 'number' when binding <as-split-area [size]="'*'">, as the @Input size is typed as number | null in the source code, though the documentation clearly states it can also be bound to '*' in pixel mode.

As a workaround, you can use $any in the template

	<as-split-area [size]="$any('*')">hello</as-split-area>

Hey @lf-novelt , if you check #289 you can see where it’s set. Once I finish that PR it will work without the workaround.
