#6 Consent form signature overlapping with text

Signature overlaps text. Has to do with specified offset of the signature in GettingStartedActivity.java. Should find a way of finding "Participant's signature:" text label offset to base ourselves off of that. Found on Pixel 3a AVD (API 30, x86). Check for constructing an `com.itextpdf.text.Image` with `absoluteX` and `absoluteY` hardcoded instead? [More info here](https://api.itextpdf.com/iText5/java/5.5.13/com/itextpdf/text/Image.html).
