Rate of migration followed by survival

1 2	lambda_invasion(i, K, m, r1, r2, migration_type = 0, death_rate = 1, d = NA)

`i`	number of cells of the focus type
`K`	deme carrying capacity
`m`	migration rate per cell, relative to birth rate
`r1`	birth rate of cells in the destination deme, relative to reference birth rate
`r2`	birth rate of migrating cells, relative to r1
`migration_type`	0 or 1 (see details)
`death_rate`	death rate of migrating cells, relative to death rate of cells in destination deme
`d`	migration distance relative to 1/sqrt(K); if NA then d is set to sqrt(K)

If migration_type = 0 (meaning that migration rate is correlated with birth rate) then the migration rate will be multiplied by a factor of r2 * r1. Otherwise no adjustment will be made.

The rate of migration followed by survival, when $i$ cells are attempting to migrate.
