Added Greek

[JoeDelK]

Added Greek characters and Greek Dictionary.

We created the dictionary based on these corpus:
https://www.bcbl.eu/en/subtlex-gr
https://inventory.clarin.gr/corpus/870

gre_char.txt
gre.txt

Particularities of the greek language:
-Have their own alphabet
-Sigma character ("σ") at the end of the word is written ("ς")
-Greek question mark is ";" instead of "?"
-They have accents and umlauts. Accents always "´" in all the vowels , except for capital letters that they look like this "Ά,Έ,Ή,Ί,Ό,Ύ,Ώ". Umlauts only in Ípsilon (Υ,υ) and Iota (Ι,ι), can be joined with the accents ("Ϊ, ΐ, ϊ,Ϋ,ϋ,ΰ").

Can we call this on easyocr.Reader()?

[kvasilopoulos]

Hi, judging from this issue I would assume that Greek is implemented but when:

import easyocr
reader = easyocr.Reader(['gre', 'en'])

I get the following:

[ValueError: ({'gre'}, 'is not supported')]()

I also tried ell, el and gr.
Thanks!

First of all thank you for this library.
Secondly, what about the Greek language which is in development?
