allow configuration of multiple set of dynamic context

[ForgottenR]

🚀 Feature Proposal

allow configuration of multiple set of dynamic context instead of only being able to configure a default context now.

Motivation

contextDefaultValues is good but not enough under many circumstances

Example

allow configuration like

contextValues={'gender':['male','female'],'color':['red','blue','yellow']}

for source files, maybe utilize some comment to specify which context set to use like

// i18-next-scanner-use-context-values color
 t('some key',{context:someData.color})
// i18-next-scanner-use-context-values gender
 t('another key',{context:someData.gender})
