Fixing Manifest Parsing - Shifting from axmlprinter to axmlparser (#180)

**Description:**
Some apps were failing with reason `Failed to parse Manifest file`
Turns out that `AxmlResourceParser` from `android4Me` is very outdated
and does not work well in all cases.
Hence have removed `axmlprinter` and migrated code to use `AxmlParser`
from `ManifestEditor` by `WindySha`.

Remove mandatory original signature check (#185)

We are unnecessary fetching original signature even when signature
bypass level is not greater than 0. Due to which some apps which were
not signed were failing to be patched with error "get original signature
failed".

fix: only add QUERY_ALL_PACKAGES permission when useManager is true (#195)

Revert "Handling duplicate System.load calls" (#202)
