devel/py-pyleri: import py-pyleri-1.4.1

Pyleri is an easy-to-use parser created for SiriDB. We first used
lrparsing and wrote jsleri for auto-completion and suggestions in
our web console. Later we found small issues within the `lrparsing`
module and also had difficulties keeping the language the same in
all projects. That is when we decided to create Pyleri which can
export a created grammar to JavaScript, C, Python, Go and Java.
