Fix Manifest Parse Failure (#151) 

Recently encountered Multiple apps where LSPatch failed to parse
AndroidManifest.xml. Upon further debugging found that we throw an error
when style sizes don't adhere to a 4-byte boundary. We can safely ignore
this and move forward since we are anyways not using `block.m_styles`
anywhere in the code. Have checked multiple other AXML parsers wherein
they too do the same thing
